Equiluminant

Equiluminant (pronounced ee-kwuh-loom-uh-nuhnt)

(1) In optics, the quality of two or more objects or phenomenon being equally luminant.

(2) Figuratively, two or more people being judged equally illustrious, attractive, talented etc.

1860s: The construct was equi- +‎ luminant.  As an adjective, luminant means "that which illuminates; that which is luminous" while as a noun it describes "an illuminating agent".  Luminant was from the Latin verb lūminant, the third-person plural present active indicative of lūminō, the construct being lūmen, from the Proto-Italic louksmən, from the primitive Indo-European léwk-s-mn̥, from the root lewk- (bright) +‎ -ō (appended to form agent nouns).  The accepted synonym is isoluminant and equiluminescent is the alternative form.  When used figuratively, although it would make no sense in science, the comparative is “more equiluminant” and the superlative most “equiluminant”.  Equiluminant & equiluminescent are adjectives and equiluminance is a noun; the noun plural is equiluminances (which some list as non-standard).

The prefixes: equi-, homo-, peri- & iso-

The prefixes “equi-”, “homo-”, “peri-” & “iso-” are all used to in same way suggest a concept of sameness or equality, but by tradition and convention, are used in different contexts to produce different meanings or emphasis:  Equi- is used to indicate equality, evenness, or uniformity and is often seen in mathematical, scientific & technical publications to describe something is equal in measure or evenly distributed such as equilateral (a shape having all sides of equal length, equidistant (being at equal distances from two or more points) & equilibrium (a state of balance where opposing forces or influences are equal).  Homo- is used to imply “same” or “alike” and thus sameness or (sometimes by degree) similarity.  In technical use it is a standard form in biology, chemistry & the social sciences to indicate sameness in kind, structure, or composition and by far the most common modern use is in the now familiar “homosexual” which in many jurisdictions is now a proscribed (or at least discouraged) term because of negative associations (“homo” as a stand-alone word also having evolved as a slur used of, about or against homosexual men).

The uses of the prefix are illustrated by homogeneous (composed of parts or elements that are all of the same kind, homologous (having the same relation, relative position, or structure) & homonym (in linguistics words which sound the same or are spelled the same but have different meanings).  Iso- is used to denote equality, uniformity, or constancy in terms of specific characteristics like size, number, or configuration and is most used in scientific and mathematical publications.  Examples of use include isometric (having equal dimensions or measurements, isothermal (having constant temperature) & isosceles (having two sides of equal length).  Peri- is used to denote “surrounding or enclosing”, or “something near or around a specific area or object”, examples including perimeter (the continuous line forming the boundary of a closed geometric figure), periscope (an optical instrument for viewing objects that are above the level of direct sight, using mirrors or prisms to reflect the view & peripheral (relating to or situated on the edge or periphery of something.  So equi-focuses on equality in measure, distance, or value, homo- focuses on sameness in kind, structure, or composition, iso- focuses on equality or uniformity in specific characteristics or conditions while peri- :focuses on surrounding or enclosing, or being near or around something.  For most purposes equi- & iso- can be used interchangeably and which is used tends to be a function of tradition & convention.

Equiluminant colors

An example the equiluminant in blue & orange.  In color the text appears at the edges to "shimmer" or "vibrate".  When re-rendered in grayscale, because the value of the luminance is so close, the two shades become almost indistinguishable.

In optics, “equiluminant” is a technical term used to colors with the same (or very similar) luminance (brightness) but which differ in hue (color) or saturation (intensity).  The standard test for the quality is to convert a two-color image to grayscale and, if equiluminant, the colors would appear nearly indistinguishable because they share the same level of “lightness”.  It’s of some importance in fields as diverse as military camouflage, interior decorating, fashion, astronomy and cognitive psychology.  In the study of visual perception, when colors are equiluminant, the human visual system relies primarily on the differences in hue and saturation (rather than brightness) to distinguish between them and this can create challenges in perception; in many cases, the brain will struggle to segregate colors based solely on luminance; essentially, there is a lack of information.

An enigmatic abstraction (2024) by an unknown creator.  This is an example of the use of non-equiluminant shades of orange & blue, the original to the left, copy rendered in gray-scale to the right.

In art and design, the quality of equiluminance can be exploited to create visual effects, the perception of some “shimmering” or “vibrating” at the edges where colors meet actually a product of the way the different hues are perceived by the brain to be “less defined” (a process not dissimilar to the “grayscaling”) and thus “dynamic”, lending the impression of movement even in a static image, especially if seen with one’s peripheral vision.  While a handy device for visual artists, it can be something of some significance because the close conjunction of equiluminant colors can make certain visual tasks more difficult, most obviously reading text or distinguishing shapes and objects.  All that happens is the extent of the luminance contrast can create a perception of fuzziness at the edges of shapes which means some people can suffer a diminished ability to distinguish fine details and the smaller the object (text, numerals or geometric shape), the more acute the problem.  The phenomenon has been well researched, scientists using the properties in equiluminant colors to study how the brain processes color and the findings have been important in fields like instrumentation and the production of warning signs.

1974 was the last year in which the big-block engines were allowed to run in NASCAR and the big-block era (1962-1973) was NASCAR's golden age.  Richard Petty (b 1937) used a "reddish orange" to augment his traditional blue when he switched from Plymouth to Dodge as the supplier of his NASCAR stockers in the early 1970s.  His team was actually sponsored by STP rather than Gulf and STP wanted their corporate red to be used but in the end a "reddish orange" compromise was negotiated.  However, when he licenced the Northern Tool Company to sell a "Richard Petty" jack, the shade used appeared to be closer to the classic "Gulf orange".

Sexy Lamborghinis in a not quite equiluminant color combination following those of the Gulf Western racing teams: 1964 1C TL tractor (top) and 1968 1R tractor (bottom).

Lamborghini had been making tractors and other farm equipment since 1948 when first its track-drive models appeared in 1955, the 1C-TL produced between 1962-1966.  Unrelated to that model cycle, it was in 1966 Lamborghini unveiled the sensational Miura (1966-1973), powered by a transversely located, mid-mounted, 3,929 cm³ (240 cubic inch) V12 engine which sucked prodigious quantities of gas (petrol) through four triple throat downdraft Weber carburetors, each of which was needed to satiate the thirst.  The power was sent to the road via a five-speed transaxle which shared it's lubrication with the engine (shades of the BMC Mini (1959-2000) which turned out to be a bad idea and one not corrected until the final run as the Miura SV (1971-1973).  To achieve the stunning lines, mounting the V12 transversely was the only way to make things fit and the engineering was a masterpiece of packaging efficiency but it resulted in the car displaying some curious characteristics at high speed.  The specification of the 1C TL Tractor was more modest although quite appropriate for its purpose; it was powered by an air-cooled 1,462 cm³ (89 cubic inch) which delivered power to the rear portal axle and drive sprockets via a dual-range, three-speed manual transmission.  However, being a diesel, there was of course fuel-injection (by Bosch), an advance Lamborghini's V12s didn’t receive until 1985 when US emission-control regulations compelled the change.  This version of 1R tractor is known as the cofano squadrato (squared hood (bonnet)); produced between 1966-1969, it replaced the earlier 1R (1961-1965) which featured a rounded hood.  The earlier model seems not retrospectively to have been christened but presumably it would have been the cofano arrotondato (rounded hood), proving everything sounds better in Italian.  An Italian could read from a lawnmower repair manual and it would sound poetic.

Not all agreed all Italians sounded so mellifluous.  In the entry for 10 January 1927 detailing a journey on the Brindisi-Rome train, the novelist Evelyn Waugh (1903-1966) noted in his diary (edited by Michael Davie (1924-2005) and published in 1976): “…a woman with the smile of a Gioconda and the voice of a parrot.  We seem to have stopped at every station in Italy, all decorated with grubby stencilled pictures of Il Duce [Benito Mussolini (1883-1945; Duce (leader) & Prime-Minister of Italy 1922-1943)] looking as if they were advertising Hassals[?] Press Art School.  All common Italian women have voices like parrots.”  By then, maybe the Duce had “made the trains run on time” so there would have been that.  The mention of “Giocondo” was an allusion to the Italian noblewoman Lisa del Giocondo (1479–1542); her name was given to the Mona Lisa, her portrait commissioned by her husband and painted by Leonardo.

A most uncommon Italian: The Mona Lisa (circa 1503), oil on white poplar panel by Leonardo da Vinci (1452–1519).

The John Hassall Correspondence Art School was a London art education institution established early in the 20^th century by the illustrator John Hassall (1868–1948) and Waugh, thinking himself both and “artist” and connoisseur of fine art, had little regard for “commercial art”.  In those years however, there was something of a boom in “poster art” and, with growing demand for graphic artists, the school filled a niche and its popularity (and profitability) increased as correspondence courses, were added, permitting students to learn via mail; conceptually, it was the same idea as “on-line education”.  What came to be called the “Hassall method” (characterized by the flat colors enclosed by thick black lines) would become an identifiable motif in early art deco.  Being quintessentially “upper middle class”, Waugh had to resort to terms like “common”, “lower class” or “lower middle class” to disparage those he thought socially beneath him; unlike members of the upper class (aristocrats, gentry, the genuinely rich etc), he couldn’t hardly use “middle class” as a slur as they could.  On 16 July 1956 he expressed his pleasure the woman buying his house was willing also “…to take over cows and peasants if required.”  Seldom did he miss an opportunity to make some mention of his superior tastes, his entry of 12 February, 1961 recording with obvious glee the “…great pleasure resulting from being rid of servants – one can throw away all the presents they have given one.”  Confident in the discernment of his readers, he didn’t bother to write “ghastly presents”.

As everybody knows, in Mean Girls (2004), there's an example or reference point for just about every known sociological, zoological, linguistic, political, scientific, botanical, geological or cosmological phenomenon yet observed.  Here, Lindsay Lohan in baby pink and powder blue illustrates an instance of equiluminance.

At scale, equiluminance doesn’t have to be obvious for it still to have desirable “side effects” and while it’s often noted two specific hues ((1) the blue Llewellyn Rylands pigments 3707 (Zenith Blue, replicated by Dulux as “Powder Blue”) & (2) the orange Rylands pigments 3957 (Tangerine, replicated by Dulux as “Marigold”)), that their use in combination appears so often on cars, motor-cycles and other stuff with wheels is due less to the claim the shades seem at the edge to “vibrate” that the striking combination appearing on some of the Gulf Oil sponsored Ford GT40s and Porsche 917s during sports car racing’s golden era (1950-1972).  Given the surface area involved, the effect is probably imperceptible when viewed at close range but the science does suggest that at speed (and these were fast machines), at the typical viewing range found on racetracks, there was what the optical analysts call “visual pop”, something which heightens the brain’s perception of motion.

Ford GT40 chassis# 1075, winner of the 1968 & 1969 Mans 24 hour endurance classic in Gulf racing livery.

Gulf's colors were not equiluminescent.  The company's original "corporate color scheme" had been a dark blue & orange combo but Gulf was an acquisitive conglomerate and in late 1967 it took over the Wilshire Oil Company of California, the signature colors of which were powder blue and orange, something which Gulf’s management thought “more exciting” and better suited to a racing car.  The change was made for the 1968 season with the Fords now running as five-litre (305 cubic inch) sports cars, governing body having banned the seven-litre engines the cars previously had used (under a variety of names, motorsport has for decades been governed by some of world sport’s dopiest regulatory bodies).  In the Gulf colors, fitted with 302 cubic inch (4.9 litre) engines, Ford GT40 Mark I (chassis #1075) won the Le Mans 24 hour endurance classic in 1968 & 1969 (repeating the brace Ford had achieved with the 7.0 litre (427 cubic inch) Mark II & Mark IV versions in 1966-1967), the first time the same car had achieved victory twice.  In 1968, #1075 won the BOAC International 500, the Spa 1000-kilometer race, and the Watkins Glen 6-hour endurance race, while in 1969 it also took the Sebring 12-hour race, a remarkable achievement for a race car thought obsolescent.  The livery has since been much replicated, including on many machines which have never been near a race track.

1971 Porsche 917K in Gulf Racing livery.  The fins were added to improve straight-line stability and were strikingly similar to those which appeared on some late 1950s US Chryslers although the aerodynamic properties of those were dubious, despite corporate claims.

Interestingly, the team painting the GT40s were aware of the issue created by equiluminant colors and knew that when photographed in certain conditions, the shades could tend thus.  As a matter of professional pride, they didn’t want it thought they’d created something with “fuzzy edges” so deliberately was added a dark blue hairline-border around the orange, reducing the optical illusion to ensure that when photographed, everything looked painted with precision.  When the Gulf team in 1970 switched to using Porsche 917s for the World Sports Car championship, they adopted the expedient of a black line of definition between the blue & orange so the whole enduring appeal of the combination lies just in the striking contrast and relies not at all on any tendency to the equiluminant.

Ford GT Heritage Edition First Generation (left) and Second Generation (right). 

Little more than 100 GT40s were built but Ford noted with interest the ongoing buoyancy of the replica market, as many as 2,000 thought to have been built in a number of countries (although that's dwarfed by number of replica Shelby American Cobras; it's believed there are 50-60,000-odd of them, a remarkable tribute to the 998 originals).  In the twenty-first century, the company decided to reprise the design but the new GT (2004-2006) was hardly a clone and although it shared the basic mechanical layout and the shape (though larger) was close, it was a modern machine.  The car wasn’t called GT40 because the rights to the name had ended up with another company and Ford declined to pay the demanded price.  Over 4000 were built and one special run was a tribute to the 1968-1969 cars in Gulf livery, 343 of the “Heritage Editions” produced.  A second generation of GTs was produced between 2016-2022 and was very modern, the demands of the wind-tunnel this time allowed to prevail over paying tribute to the classic lines of the 1960s.  Although the supercharged 5.4 litre V8 didn’t return and the new car used a turbocharged 3.5 litre (214 cubic inch) V6, it outperformed all its predecessors over the last 60-odd years (all the original GT40 chassis built between 1964-1969) including the 427 cubic inch monsters that won at Le Mans in 1966 & 1967 so it took decades, but eventually there really was a "replacement for displacement".  The V6 also was used also in pick-up trucks which doesn't sound encouraging but versions of the small & big block V8s used in the GT40s also saw similar service, the latter even first appearing in the doomed Edsel.  Production of the second generation was limited to 1350 units, 50 of which were “Heritage Editions” in the Gulf colors, one of several “limited editions”.

Foxbat

Foxbat or fox-bat (pronounced foks-bat)

(1) As Foxbat, the NATO (North Atlantic Treaty Organization) reporting name for the Soviet-era MiG-25 (Mikoyan-Gurevich MiG-25) high-altitude supersonic interceptor and reconnaissance aircraft.

(2) A common name for members of the Megachiroptera (the Pteropus (suborder Yinpterochiroptera), a genus of megabats), some of the largest bats in the world.

Fox is from the Middle English fox, from the Old English fox (fox), from the Proto-West Germanic fuhs, from the Proto-Germanic fuhsaz (fox), from the primitive Indo-European púḱsos (the tailed one), derive possibly from puḱ- (tail).  It was cognate with the Scots fox (fox), the West Frisian foks (fox), the Fering-Öömrang North Frisian foos, the Sölring and Heligoland fos, the Dutch vos (fox), the Low German vos (fox), the German Fuchs (fox), the Icelandic fóa (fox), the Tocharian B päkā (tail, chowrie), the Russian пух (pux) (down, fluff), the Sanskrit पुच्छ (púccha) (source of the Torwali پوش‎ (pūš) (fox) and the Hindi पूंछ (pūñch) (tai”).

Bat in the context of the animal was a dialectal variant (akin to the dialectal Swedish natt-batta) of the Middle English bake & balke, from the North Germanic. The Scandinavian forms were the Old Swedish natbakka, the Old Danish nathbakkæ (literally “night-flapper”) and the Old Norse leðrblaka (literally “leather-flapper”).  The Old English word for the animal was hreremus, from hreran (to shake) and it was known also as the rattle-mouse, an old dialectal word for "bat", attested from the late sixteenth century.  A more rare form, noted from the 1540s, was flitter-mouse (the variants were flinder-mouse & flicker-mouse) in imitation of the German fledermaus (bat) from the Old High German fledaron (to flutter).  In Middle English “bat” and “old bat” were used as a (derogatory) term to describe an old woman, perhaps a suggestion of witchcraft rather than a link to bat as "a prostitute who plies her trade by night".  It’s ancient slang and one etymologist noted the French equivalent hirondelle de nuit (night swallow) was "more poetic".  To “bat the eylids” is an Americanism from 1847, an extended of the earlier (1610s) meaning "flutter (the wings) as a hawk", a variant of bate.  Fox-bat is a noun; the noun plural is fox-bats.  When used of the MiG-25 (as "Foxbat", the NATO reporting name), it's a proper noun and thus used with an initial capital.

Fox-bat in flight.

The term fox-bat or flying fox, (genus Pteropus), covers some sixty-five bat species found on tropical islands from Madagascar to Australia and north through Indonesia and mainland Asia.  Most species are primarily nocturnal and are the largest bats, some attaining a wingspan of 5 feet (1.5 m) with an overall body length of some 16 inches (400 mm).  Zoologists list fox-bats as “Old World fruit bats” (family Pteropodidae) that roost in large numbers and eat fruit and are thus a potential pest, many countries restricting their importation.  Like nearly all Old World fruit bats, flying foxes use sight rather than echolocation, a physiological process for locating distant or invisible objects (such as prey) by means of sound waves reflected back to the emitter by the objects) to navigate, despite the largely nocturnal habit of most species.  In the database maintained by the International Union for Conservation of Nature and Natural Resources (IUCN), about half of all flying fox species are listed as suffering declining populations, 15 said to be vulnerable and 11 endangered. The fox-bats were previously classified in the suborder Megachiroptera, but most researchers now place them in the suborder Yinpterochiroptera, which also contains the superfamily Rhinolophoidea, a diverse group that includes horseshoe bats, trident bats, mouse-tailed bats, and others.

MiG-25 (Mikoyan-Gurevich MiG-25).

Once the most controversial fighter in the skies, there was so much mystery surrounding the MiG-25 that US, British and NATO planners spent years spying on it with a mixture of awe and dread.  Conceived originally by Soviet designers to counter the threat posed by Boeing’s B-70 Valkyrie bomber, development continued even after the B70 project, rendered redundant by advances in missile technology, was cancelled.  First flown in 1964 and entering service in 1970, nearly 1200 were built and were operated by several nations as well as the USSR.  Able (still) to outrun any other fighter, only the US Lockheed SR-71 Blackbird was faster but fewer than three dozen of those were built and those were configured only for strategic reconnaissance.  When first the West became aware of the Foxbat, it caused quite a stir because, combining stunningly high speed with high altitude tolerance and a heavy weapons load, it did appear to be the long-feared platform which would render Soviet airspace immune from US penetration.  It was the threat the Foxbat was thought to pose which was influential in the direction pursued by US engineers when developing the McDonnell Douglas F15.

The Foxbat however never realized its apparently awesome implications. Because the original design brief was to produce a device which could combat the fast, high-flying B-70, many of the characteristics desirable in a short-range interceptor were neglected in the quest for something which could get very high, very quickly.  At that it was a breathtakingly successful but there were compromises, the fuel burn was epic and, with a very high take-off and landing speed, it could operate only from the longest runways.  Still, at what it was good at it was really good and its very presence meant the US had to plan any mission within range of a Foxbat, cognizant of the threat it was thought to present.  Unbeknown to the West, at lower altitudes it presented little threat and was no dog-fighter; it was essentially a dragster built for the skies, faster in a straight line than just about anything but really not good at turning.  Its design philosophy was essentially the same as the Lockheed F-104 Starfighter, a US supersonic interceptor which first flew in 1954 with over 2,500 built and supplied to many air forces, the last of which wasn’t retired from active service until 2004.  An uncompromising machine built for speed, pilots dubbed it the “winged missile” and that assessment was not unrelated to it later gaining the nickname “widow-maker”; those who flew the thing described the characteristics it exhibited in low speed turns as: “banking with intent to turn”.

It wasn’t until 1976 when a Soviet defector landed a new Foxbat in Japan in 1976 that US engineers were able to examine the airframe and draw an understanding of its capabilities.  What their analysis found was that the limitations in Soviet metallurgy and manufacturing techniques had resulted in a heavy airframe, one which really couldn’t maneuver at high speeds, and handled poorly at low altitudes. The surprisingly primitive radar was of limited effectiveness in conventional combat situations against enemy fighters, which, combined with the low altitude clumsiness meant that its drawbacks tended to outweigh the advantage it had in sheer speed at altitude, something which meant less to the US since missiles had replaced the B-70 strategic bomber (which never entered production).

In its rare combat outings, those advantages did however confer the occasional benefit.  In 1971, a Soviet Foxbat operating out of Egypt used its afterburners to sustain Mach 3 for an extended duration, enabling it to outrun three pursuing Israeli F4-Phantoms and one downed a US Navy F/A-18 Hornet during the first Gulf War (1991).  During the Iran-Iraq War (1980-1988), the Iraqi Air Force found them effective against old, slow machinery but sustained heavy losses when confronted with the Iran’s agile F-14 but most celebrated was probably the Foxbat’s success during the Gulf War in claiming both of the last two American aircraft lost in air-to-air combat.  Otherwise, the Foxbat has at low altitude proved vulnerable, the Israeli Defense Force (IDF) shooting down several in the war over Lebanon (1981) although they have of late been used, most improbably, in a ground attack role in the Syrian Civil War, the Syrian Arab Air Force, lacking a more appropriate platform, pressing the Foxbats into a ground support role, in at least one case using air-to-air missiles to attack ground targets.  The Soviet designers took note of the operating environment when developing the Foxbat’s successor, the MiG-31 (NATO reporting name Foxhound), a variant which sacrificed a little of the pure speed and climb-rate in order to produce a better all-round fighter.

Usually unrelated: 1957 Morris Minor Traveller (left) and 1960 Jaguar XK150 FHC (right).  Stations wagons with wood frames (real and fake) are in the US called "woodies" but the spelling "woody" also appears in UK use.  Although between 1968-1973, there were “badge-engineered” Versions of the Minor’s commercial derivatives sold as the Austin 6cwt & 8cwt Van & Pick up, all the “woodies” were Morris Travellers.

Although for the whole of the Jaguar XK150’s production run (1957-1961) the Morris Minor Traveller (1952-1973) was also being made in factories never more than between 20-60 odd miles (32-100 km) distant, so different in form and function were the two it’s rare they’re discussed in the same context.  One was powered by an engine which had five times won the Le Mans 24 hour endurance classic while the other was one of several commercially-oriented variants of a small, post-war economy car, introduced in the austere England of 1948.  The Traveller did however have charm and it was also authentic in its construction, the varnished ash genuinely structural, an exoskeleton which provided the strength while the panels behind were there just to keep out the rain.  By contrast, by the mid-1950s, the US manufacturers had abandoned the method and produced “woodies” with a combination of fibreglass (fake timber) and DI-NOC, (Diurno Nocturna, from the Spanish, literally “daytime-nighttime” and translated for marketing purposes as “beautiful day & night”) appliqué, an embossed vinyl or polyolefin material with a pressure-sensitive adhesive backing produced since the 1930s and perfected by Minnesota Mining & Manufacturing (3M).

In phased releases over 1957-1958, Jaguar made available the usual three versions of its XK sports car, the DHC (drophead coupé, a style which elsewhere was usually called a cabriolet or convertible) and FHC (fixed head coupé, ie coupé), later joined by the more minimalist OTS (open two-seater, a roadster) and the line was a link between flowing lines of the inter-war years and the new world, celebrated by the E-Type (1961-1974) which created such a sensation upon debut at the 1961 Geneva Motor Show.  One sometimes unappreciated connection between the XKs (XK120: 1948-1954, XK140: 1954-1957 & XK150: 1957-1961) and E-Type is neither was envisaged as the long-term model both became.  The XK120 had been shown at the 1948 London Motor show with the purpose of drawing attention to the new XK straight-six (which would serve in vehicles as diverse as racing cars, limousines and fire engines until 1992) but such was the public response it was added to the factory catalogue, the early models hurriedly built in aluminium to satisfy demand.  Later, Jaguar hadn't believed there would be a market for more than a few hundred E-Types so it was not designed in a way optimized for mass-production which was embarked upon only because demand was so high.  Many of the car's quirks and compromises remained part of the structure until the end of production more than a decade later.   

Minor modification: 1960 Jaguar XK150 3.4 Shooting Brake (“Foxbat”).

The Morris Minor Traveller was the last true woodie in production and is now a thing in the lower reaches of the collector market but there's one less available for fans because of a sacrifice to a project by industrial chemist and noted Jaguar enthusiast, the late Geoffrey Stevens, construction undertaken between 1975-1977. He wanted the Jaguar XK150 shooting brake the factory never made so blended an XK150 FHC with the rear compartment of a Morris Minor Traveller of similar vintage.  Mr Stevens in 1976 dubbed his creation “Foxbat” because, just as a MiG-25 landing in Japan was an event so unexpected it made headlines around the world, he suspected that in the circles he moved, a timber-framed XK150 shooting brake would be as much a surprise.  In that he proved correct and the unique shooting brake has been restored as a charming monument to English eccentricity, even the usually uncompromising originality police among the Jaguar community (mostly) fond of it.  In a nice touch (and typical of an engineer’s attention to detail), a “Foxbat” badge was hand-cut, matching the original Jaguar script.  Other than the hybrid coach-work, the XK150 is otherwise “matching-numbers” (chassis number S825106DN; engine number V7435-8).   

On the Wings of a Russian Foxbat: Deep Purple bootleg, 1977.

The origin of the term “bootlegging” dates from the late eighteenth century when it was used by British customs and excise officers to describe the trick smugglers used hiding valuables in their large sea-boots.  Since then, it’s been applied variously including (1) the distilling, transporting and selling of unlawful liquor (2) unlicensed copies of software and (3) unauthorized recordings of music and film.  In music, bootleg recordings began to appear in some volume in the 1960s and originally were often from live performances.  Often created from tapes of dubious quality with little or no editing, these bootlegs generally were tolerated by the industry because they tended to circulate among fans who anyway purchased the official product and were thought of just a form of free promotional material.  Later, when things became more organized and bootleggers began distributing replicas of official releases, the attitude changed and for decades the software industry fought ongoing battles against bootleg copies (which in some non-Western markets represented in excess of 90% of installations).

On the Wings of a Russian Foxbat, re-released (in re-mastered form with bonus tracks) in 1995 as Live in California, Long Beach Arena, 1976.

Taken from a performance by the English heavy metal band Deep Purple at the Long Beach Arena, Los Angeles on 27 February 1976, the bootleg On the Wings of a Russian Foxbat was released in 1977 and was another example of the effect on popular culture of the Soviet pilot’s defection.  The link with the event in Japan was that the quality of the band’s performance was unexpectedly good, their reputation at the time not good (they would break-up only weeks after the Long Beach show).  Additionally, the sound quality was outstanding (certainly by the usual bootleg standards), something not then easy to achieve in an outdoor venue with a raucous audience.  Curiously, the original On the Wings of a Russian Foxbat bootleg used for the cover art a picture of unsmiling soldiers from the PLA (People’s Liberation Army) from the Republic of China (then usually called “Red China” or “Communist China); presumably the bootleggers decided the star on the caps was “sufficiently Russian”.  In 1995, re-mastered, the recording (with a few bundled “extras”) was re-issued as an “official” release, the fate of many a bootleg with a cult-following.  With memories of the diplomatic incident in 1976 having faded, although On the Wings of a Russian Foxbat still appeared on the cover, the album was marketed as Live in California, Long Beach Arena, 1976.

Otrovert (pronounced ott-roh-vert)

A person unable to feel a connection to social groups or collectives; despite being welcomed and included in social settings, they feel like outsiders.

2025: A coining by US psychiatrist Dr Rami Kaminski (b 1954), who first used the word in his book his book The Gift of Not Belonging (2025), the construct being the Spanish otro (other; another) + -vert.  Otro was from the Latin alter, altera & alterum (the other), ultimately from the primitive Indo-European hélteros (the other of two); it may be compared with the Portuguese outro (from the Old Galician-Portuguese outro, from the Latin alterum (the other)) and the French autre (from Old French autre (another), from the Latin alterum).  The –vert suffix was from the Latin vertere (to turn) and was used to refer to a person with a particular personality which manifests when in the presence of others.

Otrovert is a noun; the noun plural is otroverts.  Because otrovert is a “hot word” (newly coined or an adaptation of an existing word and one which has in a short time become popular), most lexicographers are tagging it as “provisional”, the majority of “hot words and phrases” (think “six-seven”) fading from use and never gaining critical mass.  Even the idea of “popular: had (in this context) shifted because whereas once it could take months or years for a word or phrase to spread into general use, on the various platform on the internet, proliferation can be close to instant.  However, the tools used to assess “use” are rather brute-force and often are counting appearances in “lists” rather than “general use”.  For those reasons, in the technical sense, derived forms really don’t (yet) exist but if constructed the list (based on the model of other “-verts”) might include the nouns otrovertist, otroverting & otrovertness, the verb & adjective otroverted, adjectives otrovertish & otrovertesque & otrovertive and the adverbs otrovertedly & otrovertly.

Google ngram (a quantitative and not qualitative measure): Because of the way Google harvests data for their ngrams, they’re not literally a tracking of the use of a word in society but can be usefully indicative of certain trends, (although one is never quite sure which trend(s)), especially over decades.  As a record of actual aggregate use, ngrams are not wholly reliable because: (1) the sub-set of texts Google uses is slanted towards the scientific & academic and (2) the technical limitations imposed by the use of OCR (optical character recognition) when handling older texts of sometime dubious legibility (a process AI should improve).  Where numbers bounce around, this may reflect either: (1) peaks and troughs in use for some reason or (2) some quirk in the data harvested.

An ambivert is a person neither clearly extroverted nor introverted, but has characteristics of each, the construct being ambi- +‎ -vert.  Ambi- was from the Latin ambo (both) and was a doublet of the New Latin amphi-, from the Ancient Greek ἀμφί (amphí) (on both sides).  The dexter element in the Medieval Latin meant “right” and ambidexter thus was understood as “both hands being like a right hand”.  In English, the ambi- prefix is most familiar in “ambidextrous” (possessing an equal or functionally comparable ability to handle objects with both hands (in writing, music, sport etc) although it has from time to time been used figuratively (not taking sides in conflicts or being equally adept in more than one medium, genre, style etc) and even as a humorous synonym for “bisexual”.  When used in psychology, historically, ambiversion described someone with characteristics of both extroversion and introversion and thus suggested a “balanced personality”, the subject choosing to manifest the different characteristics according to what the circumstances seemed to demand.  Ambivert thus does not imply some sort of split personality or the existence of a condition like bi-polar disorder (the old manic depression) but simply reflects an individual able to undertake their social interactions in an appropriate manner.

Because the “vert words” are not really part of academic or clinical physiology, the definitions can be “elastic” and while centovert (being in the middle between introvert and extrovert) may be a synonym of ambivert, it may also be nuanced in that it suggests someone unable (or at least unwilling) to engage in introverted or extroverted behaviour, regardless of the circumstances.  A variant of the ambivert is the omnivert (someone fits into both extremes of the extroversion-introversion personality spectrum), the construct being omni + -vert.  Omni- ultimately was from the Latin omnis (all).  Again, because the “verts” are pop-psychology words there’s little to be gained from attempting to “parse the overlaps” (ie where one ends and another begins) and seems likely omniversion is simply an “enabling pre-condition” for one to possess if one is to attain the desirable “balanced state” of ambiversion.  Nobody seems yet to have coined ultravert, hypervert or ubervert but one need not spend long on social media to see the why such labels might be handy.

A self-described introvert: Lindsay Lohan explains she's an introvert; 2019 interview by broadcaster Howard Stern (b 1954).

Like other “-verts” of this ilk, otrovert was built on the model of the familiar introvert & extravert, the construct being intro + -vert.  An introvert (pronounced in-truh-vurt) is an individual who prefers (sometimes actively seeks) tranquil environments, limits social engagement and tends to a greater than average preference for solitude.  In anatomy & zoology there’s a technical meaning “a part (typically a hollow, cylindrical structure) that is or can be introverted, or turned in on itself (ie invaginate)) but the most commonly used is the psychological sense: a person characterized by concern primarily with their own thoughts and feelings.  Introverts are noted often for having a disposition that finds social engagement at least tiresome (and sometimes threatening), thus the preference for quiet solitude.  Introvert seem first to have appeared in print in the 1660s and was from the New Latin intrōvertere, the construct being intrō (within) + vertere (to turn).  The prefix intro- was from the Latin intro- (inwards) & intrā (within) + -ō (used as a verbalizer).  Although it’s not infrequent for introvert to be used as a synonym for “shy” (and in terms of observed behaviour the two phenomena can appear indistinguishable), they are definitionallly distinct.  While shyness is associated with timidity and social anxiety, introverts have a lack of interest in interpersonal engagement and a limited endurance for social contact; what that means is while the behaviours can often be the same, the underlying motivations differ.

Slaughterhouse-Five (1969) by Kurt Vonnegut.

Introvert & extrovert are popular terms of self-description but they can also be aspirational and while the classic stereotype is of the introvert who “wishes they were more outgoing” there are other types.  The US pediatrician Dr Mark Vonnegut (b 1947) wrote short stories and in one he described his father’s (the author Kurt Vonnegut (1922-2007)) desire to be a cynical, grumpy old man who despaired of humanity but could never quite manage it because of his “inherent optimism”.  As Dr Vonnegut put it, he was “…like an extrovert who wanted to be an introvert, a very social guy who wanted to be a loner, a lucky person who would have preferred to be unlucky. An optimist posing as a pessimist, hoping people will take heed.”  Explaining the difference, he added: “Introverts almost never cause me trouble and are usually much better at what they do than extroverts.  Extroverts are too busy slapping one another on the back, team building, and making fun of introverts to get much done.  Extroverts are amazed and baffled by how much some introverts get done and assume that they, the extroverts, are somehow responsible.”  On the basis of his clinical experience, he observed: “I understand perfectly why some of my autistic patients scream and flap their arms--it's to frighten off extroverts.”

An extrovert (pronounced ek-struh-vurt) is described typically as an outgoing, gregarious person who thrives in dynamic environments and seeks to maximize social engagement; in the jargon of psychology, it refers to someone characterized by extroversion; a person concerned primarily with the physical and social environment, thus the usual presentation as a person with a disposition energized through social engagement who tends to languish or chafe in solitude.  The word extrovert (the alternative spelling extravert (an example of the influence of German on psychology) is now rare) also emerged in the 1660s, the construct being extro- + vert.  In this case, extro- was a pseudo-Latinism prefix based upon the Latin extra- (outside, beyond), under the influence of the distinction between the Latin intro- (inwards) & intra- (inside; within).  In English, formations using the prefix tend to be restricted to words formed as antonyms of terms formed with intro-.

Introvert & extrovert (in their literal senses) were since the late seventeenth century used in science and medicine but both in the twentieth century entered general use when certain works by the Swiss psychiatrist, Carl Jung (1875–1961) were translated from German into English.  What seems to have given the words their greatest impetus was the appearance of commentaries on Jung written for a general audience and for these purposes binary concepts like “introvert” and “extrovert” were useful devices to encapsulate layers of meaning although the trigger may have been the 1918 paper Psycho-Analytic Study of August Comte [1798-1857; a seminal figure in sociology] by psychologist Dr Phyllis Blanchard (1895-1986).  Being a woman, Dr Blanchard has been neglected by history but, like the Austrian psychiatrist Sigmund Freud (1856-1939), Jung became what would now be called a “celebrity” psychoanalyst and that happened because advances in their field (and neurology) had made the public fascinated with the human mind and its processes (especially dreams).  Reflecting what may possibly be a professional distaste at their jargon ending up in pop-psychology texts, technical papers often use the spelling “extravert”, following Jung and his contemporaries.

The Gift of Not Belonging (2025) by Dr Rami Kaminski (b 1954).  Psychiatrist Dr Kaminski is the founder and director of the Institute for Integrative Psychiatry in New York City.

Dr Kaminski describes The Gift of Not Belonging as “…the first book to explore the distinct personality style of the otrovert - someone who lacks the communal impulse and does not fit in with any social group, regardless of its members - and to reveal all the advantages of being an otrovert and how otroverts contribute to the world.”  He explained that while otroverts enjoy deep and fulfilling one-on-one relationships, within groups they feel alienated, uncomfortable, and alone.  Unlike introverts, who crave solitude and are easily drained by social interactions, otroverts can be quite gregarious and rarely tire from one-on-one socialising; unlike loners, or people who have been marginalised based on their identity, otroverts are socially embraced and often popular - yet are unable to conform with what the group collectively thinks or cares about.  Dr Kaminski positions all this as “the great gifts of being an otrovert” by which he means someone with no affinity for a particular group is not constrained by their sense of self-worth being conditioned on the group's approval.  A champion of the otrovert, Dr Kaminski suggests they “must not be harassed to take part, but allowed to revel in their glorious difference.”

Despite vying with “psychopath” for the title of “most popular” words from psychology, neither introvert and extrovert have ever been used as diagnostic terms in the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM); that doesn’t mean they’re not used by clinicians, just that they’re not part of the formal jargon.  That might seem curious given their not infrequent appearances in the published history of personality psychology including Jung’s original typology (codified in their most refined form in the 1920s), the ubiquitous MBTI (Myers–Briggs Type Indicator) and the Big Five model, where Extraversion is one of the five major personality traits.  These frameworks are however psychological, not psychiatric.  The DSM does of course have an extensive section on personality disorders and many of the traits related to introversion & extraversion appear including in (1) Avoidant Personality Disorder (social inhibition—links superficially to introversion but is not the same thing) and Histrionic or Narcissistic Personality Disorders (social boldness—superficially “extraverted” traits).

However, what the DSM’s editors have in recent decades done is to avoid the use of potentially ambiguous labels and focus instead on behavioural criteria that may indicate impairment or pathology.  Especially since the 1970s, the DSM has acknowledged (even championed) the idea that many “things” once classified as deviant are really part of the “normal” human condition; reflecting that paradigm, introversion & extraversion came to be understood as “normal-range” personality traits, not indicators of disorder.  As a general principle, the DSM appears to restrict the use of terms to instances where they relate to clinically significant impairment (the emphasis on the effect on the patient rather than the mechanics of process).  This approach was institutionalized with the release of DSM-5 (2013) in which the model clearly had become one of trait-based personality assessment.

To make the point, there exists in DSM-5 & DSM-5-TR (2022) the “Alternative DSM-5 Model for Personality Disorders, Section III” which describes personality traits that (more or less) correspond to what popular culture calls extraversion and introversion.  The editors however avoid the two popular words and instead breaks personality into trait domains with pathological versions of ordinary traits.  What general readers think of a “introversion” now appears in the DSM as “Detachment” although this is not pathologized unless it manifests in maladaptive extremes (chronic or persistent withdrawal; avoidance of social interaction; intimacy avoidance; a reluctance to form close relationships; anhedonia (inability to experience pleasure); mistrust of others; restricted affectivity (limited emotional expression)).  So, introverts can to some degree be “happy” with their state and just prefer frequent solitude and what the DSM calls “detachment” is invoked only when the trait is causing significant impairment or distress.

In the popular imagination, “extraversion” is associated with sociability, talkativeness, outgoing behaviour, enthusiasm (ie someone who is the “life of the party”).  That’s also obviously a “spectrum condition” and the DSM has never listed a single domain which could be classed as “high extraversion” which is good because high sociability isn’t intrinsically pathological.  Rather, should extraversion becomes maladaptive or extreme, the DSM classifies it across several domains:

(1) Attention-seeking (a facet of Antagonism) which manifests especially in Histrionic Personality Disorder.  Symptoms include an excessive need for approval, dramatic or provocative behaviour and an Intense desire to be the centre of attention.

(2) Grandiosity (a facet of Antagonism) which is characteristic of Narcissistic Personality Disorder, the symptoms including social boldness (masking fragile self-esteem) and entitlement and arrogance (which, in many cases, doesn’t manifest)

(3) Impulsivity & Risk Taking (a facet of disinhibition).  This is outgoing, sensation-seeking behaviour in its pathological form and is associated with thrill-seeking, poor impulse control and a tendency to act without considering the consequences

(4) Low Detachment: This is acknowledged as the “adaptive end of Detachment” but the editors seem to list it only to “close the circle”; it’s there because logically it has to be but is certainly not treated as a disorder.

So the DSM intentionally avoids the introvert/extrovert dichotomy which is how starkly it’s understood in popular use.  This “either-or” approach obviously doesn’t map onto the way the DSM treats personality traits as spectrums with only the margins (ie the dysfunctional extremes) described.  What that does is acknowledge there is introversion & extraversion which part of the “normal” human condition and not pathological.  Additionally it’s acknowledged the behavior which in one subject may indicate “significant impairment or distress” might in another not be of concern.

Crunning & Cromiting

Crunning (pronounced khrun-ing)

In high-performance sports training, simultaneously running and crying.

Circa 2020: the construct was cr(y) + (r)unning.

Cromiting (pronounced krom-et-ing)

In high-performance sports training, simultaneously running, crying & vomiting.

Circa 2020: the construct was cr(y) + (v)omit + (runn)ing.

The verb cry was from the thirteenth century Middle English crien, from the Old French crier (to announce publicly, proclaim, scream, shout) (from which Medieval Latin gained crīdō (to cry out, shout, publish, proclaim)). The noun is from Middle English crie, from the Old French cri & crïee.  The origin of the Old French & Middle Latin word is uncertain.  It may be of Germanic origin, from the Frankish krītan (to cry, cry out, publish), from the Proto-Germanic krītaną (to cry out, shout), from the primitive Indo-European greyd- (to shout) and thus cognate with the Saterland Frisian kriete (to cry), the Dutch krijten (to cry) & krijsen (to shriek), the Low German krieten (to cry, call out, shriek”), the German kreißen (to cry loudly, wail, groan) and the Gothic kreitan (to cry, scream, call out) and related to the Latin gingrītus (the cackling of geese), the Middle Irish grith (a cry), the Welsh gryd (a scream), the Persian گریه‎ (gerye) (to cry) and the Sanskrit क्रन्दन (krandana) (cry, lamentation).  Some etymologists however suggest a connection with the Medieval Latin quiritō (to wail, shriek), also of uncertain origin, possibly from the Latin queror (to complain) through the form although the phonetic and semantic developments have proved elusive; the alternative Latin source is thought to be a variant of quirritare (to squeal like a pig), from quis, an onomatopoeic rendition of squeaking.  An ancient folk etymology understood it as "to call for the help of the Quirites (the Roman policemen).  In the thirteenth century, the meaning extended to encompass "shed tears", previously described as “weeping”, “to weep” etc and by the sixteenth century cry had displace weep in the conversational vernacular, under the influence of the notion of "utter a loud, vehement, inarticulate sound".  The phrase “to cry (one's) eyes out” (weep inordinately) is documented since 1704 but weep, wept etc remained a favorite of poets and writers.

Vomit as a verb (the early fifteenth century Middle English vomiten) was an adoption from the Latin vomitus (past participle of vomitāre) and was developed from the fourteenth century noun vomit (act of expelling contents of the stomach through the mouth), from the Anglo-French vomit, from the Old French vomite, from the Latin vomitus, from vomō & vomitare (to vomit often), frequentative of vomere (to puke, spew forth, discharge), from the primitive Indo-European root wemh & weme- (to spit, vomit), source also of the Ancient Greek emein (to vomit) & emetikos (provoking sickness), the Sanskrit vamati (he vomits), the Avestan vam- (to spit), the Lithuanian vemti (to vomit) and the Old Norse væma (seasickness).  It was cognate with the Old Norse váma (nausea, malaise) and the Old English wemman (to defile).  The use of the noun to describe the matter disgorged during vomiting dates from the late fourteenth century and is in common use in the English-speaking world although Nancy Mitford (1904–1973 and the oldest of the Mitford sisters) in the slim volume Noblesse Oblige: an Enquiry into the Identifiable Characteristics of the English Aristocracy (1956) noted “vomit” was “non-U” and the “U” word was “sick”, something perhaps to bear in mind after, if not during, vomiting. 

Run was from the Middle English runnen & rennen (to run), an alteration (influenced by the past participle runne, runnen & yronne) of the Middle English rinnen (to run), from the Old English rinnan & iernan (to run) and the Old Norse rinna (to run), both from the Proto-Germanic rinnaną (to run) and related to rannijaną (to make run), from the Proto-Indo-European hreyh- (to boil, churn”.  It was cognate with the Scots rin (to run), the West Frisian rinne (to walk, march), the Dutch rennen (to run, race), the Alemannic German ränne (to run), the German rennen (to run, race) & rinnen (to flow), the Danish rende (to run), the Swedish ränna (to run) and the Icelandic renna (to flow).  The non-Germanic cognates includes the Albanian rend (to run, run after).  The alternative spelling in Old English was ærning (act of one who or that which runs, rapid motion on foot) and that endured as a literary form until the seventeenth century.  The adjective running (that runs, capable of moving quickly) was from the fourteenth century and was from rennynge; as the present-participle adjective from the verb run, it replaced the earlier erninde, from the Old English eornende from ærning.  The meaning "rapid, hasty, done on the run" dates from circa 1300 while the sense of "continuous, carried on continually" was from the late fifteenth century.  The language is replete with phrases including “run” & “running” and run has had a most productive history: according to one source the verb alone has 645 meanings and while that definitional net may be widely cast, all agree the count is well into three figures.  The suffix –ing was from the Middle English -ing, from the Old English –ing & -ung (in the sense of the modern -ing, as a suffix forming nouns from verbs), from the Proto-West Germanic –ingu & -ungu, from the Proto-Germanic –ingō & -ungō. It was cognate with the Saterland Frisian -enge, the West Frisian –ing, the Dutch –ing, The Low German –ing & -ink, the German –ung, the Swedish -ing and the Icelandic –ing; All the cognate forms were used for the same purpose as the English -ing).

The portmanteau words crunning (simultaneously running and crying) & cromiting (simultaneously running, crying & vomiting) are techniques used in strength and conditioning training by athletes seeking to improve endurance.  The basis of the idea is that at points where the mind usually persuades a runner or other athlete to pause or stop, the body is still capable of continuing and thus signals like crying or vomiting should be ignored in the manner of the phrase “passing through the pain barrier”.  The idea is “just keep going no matter what” and that is potentially dangerous so such extreme approaches should be pursued only under professional supervision.  Earlier (circa 2015), crunning was a blend of crawl + running, a type of physical training which was certainly self-descriptive and presumably best practiced on other than hard surfaces; it seems not to have caught on.  Crunning & cromiting came to wider attention when discussed by members of the Australian Women’s Rugby Sevens team which won gold at the Commonwealth Games (Birmingham, UK, July-August 2022).  When interviewed, a squad member admitted crunning & cromiting were “brutal” methods of training but admitted both were a vital part of the process by which they achieved the level of strength & fitness (mental & physical) which allowed them to succeed.

The perils of weed.

Although visually similar (spelling & symptoms), crunning & cromiting should not be confused with "scromiting" (a portmanteau of “screaming” and “vomiting”) a word coined in the early twenty-first century as verbal shorthand for cannabinoid hyperemesis syndrome (CHS).  Hyperemesis is extreme, persistent nausea and vomiting during pregnancy, a kind of acute morning sickness and CHS presents in much the same way.  The recreational use of cannabis was hardly new but CHS was novel and the medical community initially speculated the reaction (induced only in some users) may be caused either by specific genetic differences or something added to or bred into certain strains of weed although the condition appeared to be both rare and geographically distributed.  The long-term effects are unknown except for damage to tooth enamel caused by the stomach acid in the vomit.  In October 2025, a new layer of institutional respectability was gained by the concept of scromiting when the WHO (World Health Organization) announced it had added CHS to its diagnostic manual, the first time the disorder had been granted a dedicated code.  In the US, the existence of the code meant easily it could be adopted by the US CDC (Centers for Disease Control and Prevention) and interpolated into their reporting databases, meaning physicians nationwide could identify, track and study the condition rather than listing it in the broader vomiting or gastrointestinal categories.  Although a dangerous syndrome which for generations has been suffered by a sub-set of (mostly chronic) cannabis users, despite CHS causing severe nausea, repeated vomiting, abdominal pain, dehydration, weight loss and (in rare cases), heart rhythm problems, seizures, kidney failure and death, it was only after use of the drug was made lawful in many places that increasing incidences were noted.   The data suggests in the US CHS-related vists to hospital ERs (Emergency Room) have spiked by an impressive 650% since 2016 although it’s not known to what extent this reflects the extent of the increase in use or a willingness for patients to present now there is no potential legal jeopardy.

One theory is that since “legalization” (the term somewhat misleading because on a strict constitutional interpretation the substance remains proscribed) commercial growers (some of which operate on an industrial scale) have been “improving the breed” to gain market share and historically high levels of THC (Tetrahydrocannabinol, the cannabinoid which is the most active of the psychoactive constituents) are now common in “over the counter weed, this increasing both the instance and severity of scromiting.  Intriguingly, studies of the available ER data suggested a sharp elevation in cases of CHS during the COVID-19 pandemic and that seems to have established a new baseline, vists remaining high since.  The working assumption among clinicians is the combination of stress (induced by isolation and other factors) and the access to high-potency weed (THC levels well over 20% now often detected, compared with the 5% typically during the 1990s) may have contributed to the rise.  That however remains speculative and the alternative theory is heavy, long-term cannabis use overstimulates the body's cannabinoid system, triggering the opposite of the drug’s usual anti-nausea effect.  Ceasing use is the obvious cure (strictly speaking a preventative) but one as yet not understood amelioration is a long, hot shower and although it’s wholly anecdotal, there does seem to be a link with warming the body’s surface area because those who have experimented with “breathing in steam” report no helpful effect.

Male role model: The legendary Corey Bellemore.

An athletic pursuit probably sometimes not dissimilar to the exacting business of crunning & cromiting is the Beer Mile, conducted usually on a standard 400 m (¼ mile) track as a 1 mile (1.6 km) contest of both running & drinking speed.  Each of the four laps begins with the competitor drinking one can (12 fl oz (US) (355 ml)) of beer, followed by a full lap, the process repeated three times.  The rules have been defined by the governing body which also publishes the results, including the aggregates of miles covered and beers drunk.  Now a sporting institution, it has encouraged imitators and there are a number of variations, each with its own rules.  The holder of this most illustrious world record is Canadian Corey Bellemore (b 1994), a five-time champion, who, at the Beer Mile World Classic in Portugal in July 2025, broke his own world record, re-setting the mark to 4:27.1.  That may be compared with the absolute world record for the mile, held by Morocco’s Hicham El Guerrouj (b 1974) who in 1999 ran the distance in 3:43.13, his additional pace made possible by not being delayed by having to down four beers.

Some variations of the beer mile simply increase the volume or strength of the beer consumed and a few of these are dubbed Chunder Mile (“chunder” being circa 1950s Australia & New Zealand slang for vomiting and of disputed origin) on the basis that vomiting is more likely the more alcohol is consumed.  For some however, even this wasn’t sufficiently debauched and there were events which demanded a (cold) meat pie be enjoyed with a jug of (un-chilled) beer (a jug typically 1140 ml (38.5 fl oz (US)) at the start of each of the four laps.  Predictably, these events were most associated with orientation weeks at universities, a number still conducted as late as the 1970s and the best documented seems to have been those at the University of Otago in Dunedin, New Zealand.  Helpfully, at this time, it was the site of the country’s medical school, thereby providing students with practical experience of both symptoms and treatments for the inevitable consequences.  Whether the event was invented in Dunedin isn’t known but, given the nature of males aged 17-21 probably hasn’t much changed over the millennia, it wouldn’t be surprising to learn similar competitions, localized to suit culinary tastes, have been contested by the drunken youth of many places in centuries past.  As it was, even in Dunedin, times were changing and in 1972, the Chunder Mile was banned “…because of the dangers of asphyxiation and ruptured esophaguses.”
