1250–1300: From the Middle English blister & blester (thin vesicle on the skin containing watery matter), possibly from the Old French blestre (blister, lump, bump), probably from the Middle Dutch blyster & bluyster (swelling; blister), from the Old Norse blǣstri (a blowing), dative of blāstr (swelling).  All the European forms are from the primitive Indo-European bhlei- (to blow, swell), an extension of the root bhel- (to blow, swell).  The verb emerged late in the fifteenth century in the sense of “to become covered in blisters” and the medical use (of vesicatories) meaning “to raise blisters on” is in the literature from the 1540s.  The noun & adjective vesicatory dates from the early eighteenth century was from the Modern Latin vesicularis, from vesicula (little blister), diminutive of vesica (bladder).  In historic medicine, a vesicant (plural vesicants) or vesicatory (plural vesicatories) is used as an agent which induces blistering.  Typically a chemical compound, the primary purpose was intentionally to create a blister to draw blood or other bodily fluids to the surface, often in an attempt to relieve inflammation, improve circulation in a specific area, or treat various conditions indirectly by this counter-irritation technique.  Historically, vesicatories were commonly used with substances like cantharidin (from blister beetles) being applied to the skin to achieve this effect but in modern medicine the practice is (mostly) obsolete because more effective and less invasive treatments now exist.  Blister & blistering are nouns, verbs & adjectives, blistered is a verb & adjective, and blisterlike, blisterless & blistery are adjectives; the noun plural is blisters.

1968 MGC Roadster with bulge, blister and the bulge's curious stainless steel trim.

The MGC (1967-1969) was created by replacing the MGB’s (1962-1980) 1.8 litre four cylinder engine with a 2.9 litre (178 cubic inch) straight-six, something which necessitated a number of changes, one of which was the bonnet (hood) which gained a bulge to accommodate the revised placement of the radiator and, on the left-hand side, a small blister because the forward of the two carburettors sat just a little too high to fit even with the bulge.  Because to raise the whole bulge would have the bonnet look absurd, the decision was taken just to add a blister.  A blister (in this context) is of course a type of bulge and where a blister ends a bulge begins is just a convention of use, blisters informally defined as being smaller and of a “blister-like shape”, something recalling one appearing on one’s foot after a day in tight, new shoes.  A blister (which some seem to insist on calling a “teardrop” in they happen to assume that shape) also differs from a scoop in that it’s a enclosed structure whereas a scoop has an aperture to permit airflow.  There are however some creations in the shape of a typical blister which are used for air-extraction (the aperture to the rear) but these tend to be called “air ducts” rather than blisters.  MGC’s bulged and blistered bonnet has always been admired (especially by students of asymmetry) and both the originals (in aluminium which is an attraction in itself) and reproduction items are often used by MGB owners, either just for the visual appeal or to provide greater space for those who have installed a V8.  The apparently superfluous stainless steel trim piece in the bulge (there's no seam to conceal) is believed to be a motif recalling the small grill which was in a similar place on BMC’s (British Motor Corporation) old Austin-Healey 3000 (1959-1967), the MGC created because the 3000 couldn’t easily be modified to comply with the increasingly onerous US regulations.  Because there were doubts the cost of developing a replacement would ever be recovered, the decision was taken to build what was, in effect, a six-cylinder MGB.  The considerable additional weight of the bigger engine spoiled the MGB’s almost perfect balance and although a genuine 120 mph (195 km/h) machine, the MGC was never a critical or commercial success with only 8,999 (4,542 roadsters & 4,457 coupés) produced during its brief, two season life.

Republic P-47C Thunderbolt with the original colonnaded canopy (top) and the later P-47D with blister canopy (bottom).

When the Republic P-47 Thunderbolt (1941-1945) entered service with the USAAF (United States Army Air Force) in 1942, it was the largest, heaviest, single seat, piston-engined fighter ever produced, a distinction it enjoys to this day.  However, one thing it did share with some of its contemporaries was the replacement in later versions of the colonnaded canopy over the cockpit by an all-enveloping single panoramic structure which afforded the pilot unparalleled visibility, something made possible by advances in injection molding to fabricate shapes in Perspex, then still a quite novel material.  These canopies were adopted also for later versions of the The Supermarine Spitfire (1938-1948) and the North American P-51 Mustang (1941-1946) but the historians of aviation seem never to have settled on a description, opinion divided between “bubble-top” and “blister top”.

In military aviation, “blister” is more familiar as a use to describe the transparent bulge (or dome) on the fuselage of an airplane, usually for purposes of observation or mounting a gun but used sometimes to house a rearward air extraction device.  However, because of other linguistic traditions in military design, the “blisters” used as gun mounting position were also described with other words, the use sometimes a little “loose”.  One term was barbette (plural barbettes), a borrowing from the French and used historically to mean (1) a mound of earth or a platform in a fortification, on which guns are mounted to fire over the parapet and (2) (in naval use), the inside fixed trunk of a warship's gun-mounting, on which the turret revolves and used to contain the hoists for shells and cordite from the shell-room and magazine.

Also used was turret, from the Middle English touret, from the Old French torete (which endures in Modern French as tourette), a diminutive of tour (tower), from the Latin turris.  In architecture (and later adoptions like electronic circuitry and railcar design), turrets tended to be variations of or analogous with “towers” but in military use there was a specific evolution.  The early military turrets were “siege towers”, effectively a “proto-tank” or APC (armoured personnel carrier) in the form of what was essentially a “building on wheels”, used to carry ladders, casting bridges, weapons and soldiers equipped with the tools and devices need to storm so fortified structure such as a fort or castle.  From this evolved the still current idea notion of an armoured, rotating gun installation on a fort or warship and as powered land vehicles and later flying machines (aircraft) were developed, the term was adopted for their various forms of specialized gun mountings.  In aircraft, the term blister came later, and allusion to the blister-like shape increasingly used to optimize aerodynamic efficiency, something of little concern to admiralties.

Another military blister was the cupola (plural cupolas or cupolae), from the Italian cupola, from the Late Latin cūpula (a small cask; a little tub), from the Classical Latin cuppella, from cuppa & cūpa (tub), from the Ancient Greek κύπελλον (kúpellon) (small cup), the construct being cūp(a) + -ula, from the primitive Indo-European -dlom (the instrumental suffix) and used as a noun suffix denoting an instrument.  The origin in Latin was based on the resemblance to an upturned cup, hence the use to describe the rounded top of just about any structure where no specific descriptor existed.  In military use, a cupola is basically a helmet fixed in place and that may be on a building, a ship or an armored vehicle, the function being to protect the head while offering a field of view.  Sometimes, especially in tanks or armored cars, guns or flame-throwers were integrated into cupolas and in naval gunnery, there was the special use to describe the dome-like structures protecting a (usually single) gun mounting, something which distinguished them from the larger, flatter constructions which fulfilled the same purpose for multi-gun batteries.  Turrets and cupolas are among the architectural features of Mar-a-Lago, Donald Trump’s (b 1946; US president 2017-2021) winter palace on Ocean Boulevard, Palm Beach, Florida.

Northrop P-61 Black Widow:  A prototype with the troublesome dorsal blister turret (left), the early production P-61A with the blister removed (upper right) and the later P-61B with the blister restored (lower right).

The attractive aerodynamic properties of the classic blister shape was an obvious choice for use in aircraft but even then, they weren’t a complete solution.  The Northrop P-61 Black Widow was the first aircraft designed from a clean sheet of paper as a night-fighter, cognizant of the experience of the RAF (Royal Air Force) which during the Luftwaffe’s (the German air force) Blitz of London (1940-1941) had pressed into service day-fighter interceptors.  Designed to accommodate on-board radar, the Black Widow was heavily gunned and incorporated notable US innovations such as remote control firing mechanisms.  Part of the original was a remotely-controlled blister turret on the dorsal section which proved the shape’s aerodynamic properties worked only when pointed in the appropriate direction; when pointed at right-angles to the aircraft’s centre-line, the tail section between the twin-booms suffered severe buffeting.  Accordingly, the blister turret was deleted from the early production versions but the early experience of the military confirmed the need for additional firepower and after a re-design, it was restored to the slightly lengthened P-61B.  The integration of so many novel aspects of design meant the P-61 didn’t enter service until 1944 and, as the first of its breed, it was never a wholly satisfactory night-fighter but it was robust, had good handling characteristics and offered the advantage of being able to carry a heavy payload which meant it could operate as a nocturnal intruder with a lethal disposable load.  It was however in some ways a demanding airframe to operate, the manufacturer recommending that when fully-loaded in its heaviest configuration, a take-off run-up of 3 miles (4.8 km) was required.  Although its service in World War II (1939-1945) was limited, remarkably, like the de Havilland Mosquito (DH.98), the Black Widow was also a Cold War fighter, both in service until 1951-1952 because of a technology deficit which meant it wasn’t until then jet-powered night-fighters came into service.  The Black Widow was in 1949 (by then designated F-51), the first aircraft in service in the embryonic USADC (US Air Defense Command), formed to defend the country from any Soviet intrusion or attack.

Xanax (Alprazolam), a fast-acting benzodiazepine.  It is marketed as anti-anxiety medication and supplied in blister packs.

Lindsay Lohan released the track Xanax in 2019.  With a contribution from Finnish pop star Alma (Alma-Sofia Miettinen; b 1996), the accompanying music video was said to be “a compilation of vignettes of life”, Xanax reported as being inspired by Ms Lohan’s “personal life, including an ex-boyfriend and toxic friends”.  Structurally, Xanax was quoted as being based around "an interpolation of" Better Off Alone, by Dutch Eurodance-pop collective Alice Deejay, slowed to a Xanax-appropriate tempo.

Bubbletop

Bubbletop (pronounced buhb-uhl-top)

(1) In aircraft design, a design of pilot’s canopy (originally military slang for what designers dubbed the “bubble canopy”, a Perspex molding which afforded exceptional outward visibility).

(2) An automobile using a transparent structure over the passenger compartment, replacing the usual combination of roof & windows.

(3) A descriptor of certain automobiles of the early 1960s, based on the shape rather than the method of construction, the conventional metal and glass used.

1940s: The construct was bubble +‎ top.  Bubble dates from the late fourteenth century and was from the Middle English noun bobel which may have been from the Middle Dutch bubbel & bobbel and/or the Low German bubbel (bubble) and Middle Low German verb bubbele, all thought to be of echoic origin.  The related forms include the Swedish bubbla (bubble), the Danish boble (bubble) and the Dutch bobble.  Top pre-dates 1000 and was from the Middle English top, toppe & tope (top, highest part; summit; crest; tassel, tuft; (spinning) top, ball; a tuft or ball at the highest point of anything), and the Old English top & toppa (top, summit, tuft of hair), from the Proto-West Germanic topp, from the Proto-Germanic tuppaz (braid, pigtail, end), of unknown origin.  It was cognate with the Old Norse toppr (top), the Scots tap (top), the North Frisian top, tap & tup (top), the Saterland Frisian Top (top), the West Frisian top (top), the Dutch top (top, summit, peak), the Low German Topp (top), the German Zopf (braid, pigtail, plait, top), the Swedish topp (top, peak, summit, tip) and the Icelandic toppur (top).  Alternative forms are common; bubble-top in automotive & aeronautical engineering and bubble top in fashion.  Bubbletop is a noun and bubbletopped is an adjective; the noun plural is bubbletops.

Evolution of the Mustang's bubbletop: P-51C (top), P-51 III (centre) and P-51D (bottom).

“Bubbletop” began as World War II (1939-1945) era military slang for officially was described as the “bubble canopy”, the transparent structure sitting atop the cockpit of fighter aircraft, the advantages being (1) superior visibility (the purest interpretation of the design affording an unobstructed, 360° field-of-view, (2) improved aerodynamics, (3) easier cockpit ingress & egress (of some significance to pilots force to parachute and (4), weight reduction (in some cases).  Bubbletops had been seen on drawing boards in the early days of aviation and some were built during World War I (1914-1918) but it was the advent of Perspex and the development of industrial techniques suitable for the creation of large, variably-curved moldings which made mass-production practical.  The best known early implementations were those added to existing air-frames including the Supermarine Spitfire, Republic P-47 Thunderbolt and North American P-51 Mustang.  By 1943, the concept had become the default choice for fighter aircraft and the technology was applied also to similar apparatuses used elsewhere on the fuselage where they were styled usually as “blisters”.  In the post war years it extended to other types, most dramatically in the Bell 47 helicopter where the cabin was almost spherical, some 70% of the structure clear Perspex.

The enormous and rapid advances in wartime aeronautics profoundly influenced designers in many fields and nowhere was that more obvious than in the cars which began to appear in the US during the 1950s.  Elements drawn variously from aeronautics and ballistics did appear in the first generation of genuinely new post-war models (most of what was offered between 1945-1948 being barely revised versions of the 1942 lines) but it was in the next decade the designers were able to embrace the jet-age (a phrase which before it referred to the mass-market jet-airline travel made possible by the Boeing 707 (which entered commercial service in 1958) was an allusion to military aircraft, machines which during the Cold War were a frequent sight in popular culture).  On motif the designers couldn’t resist was the bubble canopy, something which never caught on in mass-production although Perspex roofed cars were briefly offered before word of their unsuitability for use in direct sunlight became legion.

GM Firebird XP-21 (Firebird I, 1953).

Not content with borrowing the odd element from aircraft, the General Motors (GM) team decided the best way to test which concepts were adaptable from sky to road was to “put wheels on a jet aircraft” and although they didn’t do that literally, by 1953 when Firebird XP-21 was first displayed, it certainly looked as though it was exactly that.  Its other novelty was it was powered by a gas turbine engine, the first time a major manufacturer in the US had built such a thing although a number of inventors had produced their own one-offs.  When the XP-21 (re-named Firebird I for the show circuit) made its debut, some in the press referred to it as a “prototype” but GM never envisaged it as the basis for a production car, being impractical for any purpose other than component-testing; it should thus be thought of as a “test-bed”.  The bubble canopy looked as if it could have come from a US Air Force (UFAF) fighter jet and would have contributed to the aerodynamically efficiency, the 370 hp (280 kW), fibreglass-bodied Firebird I said to be capable of achieving 200 mph (320 km/h) although it’s believed this number came from slide-rule calculations and was never tested.  Despite that, in its day the Firebird II made quite a splash and a depiction of it sits atop the trophy (named after the car’s designer, Harley Earl (1893–1969), the long time head of GM’s styling studio) presented each year to the winner of NASCAR’s (National Association for Stock Car Auto Racing) premiere event, the Daytona 500.

GM Firebird II (1956).

Compared with its predecessor, the Firebird II (1956), rendered this time in titanium was almost restrained, the Perspex canopy a multi-part structure over a passenger compartment designed to seat “a family of four”.  The family might have chosen to drive mostly in darkness because the heat build-up under the midday sun would have tested the “individually-controlled air conditioning”, a system upon which comfort depended because the Perspex sections were fixed; there were no opening “windows”.  Still, even if hot, the family would have got places fast because the same 200 mph capability was claimed.

GM Firebird III (1958).

The Firebird III was displayed at the 1958 Motorama and although GM never built any car quite like it, within a season, elements of it did begin to appear on regular production models in showrooms (notably the rear skegs which Cadillac used for a couple of years) and some of its features are today standard equipment in even quite modest vehicles.  The striking “double bubbletop” never made the assembly lines although some race cars have at least partially implemented the concept.  What proved more of a harbinger was the specification, the Firebird III fitted with anti-lock brakes, cruise control, air conditioning, an automated “accident avoidance system” and instead of a steering wheel, the driver controlled the thing with a joystick, installed in a centrally-mounted “Unicontrol & Instrument Panel”.  All these were analogue-era electro-mechanical devices too bulky, fragile or expensive for mass production, wider adoption in the decades to come made possible by integrated circuits (IC) and micro-processors.

1959 Cadillac Cyclone (XP-74).

Borrowing from the Firebird II, Cadillac also used a bubble top for the Cyclone (XP-74) concept car which in 1959 toured the show circuit.  Although it was powered by the corporation’s standard 390 cubic inch (6.5 litre) V8, there was some adventurous engineering including a rear-mounted automatic transaxle and independent rear suspension (using swing axles, something not as bad as it sounds given the grip of tyres at the time) but few dwelt long on such things, their attention grabbed by features such as the bubble top (this time silver coated for UV (ultra violet) protection) which opened automatically in conjunction with the electrically operated sliding doors.  The Perspex bubble canopies from fighter aircraft never caught on for road or race cars but so aerodynamically efficient was the shape it found several niches.

1953 Ferrari F166MM Spider by Vignale (left) and 1968 MGCGT (centre & right).

Bubbles often appeared atop the hood (bonnet) to provide clearance for components inconveniently tall.  Most were centrally located (there was the occasional symmetrical pair) but the when BMH (British Motor Holdings, the old  BMC (British Motor Corporation) shoehorned their big, heavy straight-six into the MGB (1963-1980), it wouldn’t fit under the bonnet, the problem not the cylinder head but the tall radiator so the usual solution of a “bonnet bulge” was used.  However, for that to clear the forward carburetor, the bulge would have been absurdly high so a small bubble (and usually, ones this size are referred to as "blisters") was added.  It probably annoyed some there wasn’t a matching (fake) one on the other side but it’s part of the MGC’s charm, a quality which for years most found elusive although it’s now more appreciated.  For MGC owners wish to shed some weight or for MGB owners who like the look, the “bonnet with bubble” is now available in fibreglass.

The winning Ford GT40 Mark IV (J-Car) with bubble to the right, Le Mans 1967 (left) and the after-market (for replicas) “Gurney Bubble” (right).

US racing driver Dan Gurney (1931–2018) stood 6' 4" (1.9 m) tall which could be accommodated in most sports cars and certainly on Formula One but when he came to drive the Ford GT40 Mark IV it was found he simply didn’t fit when wearing his crash helmet.  The original GT40 (1964) gained its name from the height being 40 inches (1016 mm) but Mark IV (the “J-Car”, 1966) was lower still at 39.4 inches (1,000 mm).  Gurney was the tallest ever to drive the GT40 and the solution sounds brutish but fix was effected elegantly, a “bubble added to the roof to clear the helmet.  Gurney and AJ Foyt (b 1935) drove the GT40 to victory in the 1967 Le Mans 24-hour endurance classic and the protrusion clearly didn’t compromise straight-line speed, the pair clocked at 213 mph (343 km’h), on the famous 3.6-mile Mulsanne Straight (which was a uninterrupted 3.6 miles (5.8 km) until the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation and world sport’s dopiest regulatory body) imposed two “chicanes”),  Known ever since as the “Gurney Bubble”, such is the appeal that they’re now available for any GT40 replica: Like the AC Shelby Cobra, the GT40 “reproduction” industry is active and there are many times more of these than there are survivors of 105 originals.

Ferrari 250 GT “Tour de France” LWB Berlinettas by Zagato: The “double bubble” roof (left), the Hofmeister kink (centre) and the famous “Z” kink, (right).

The Italian coachbuilding house Zagato was founded in 1919 by Ugo Zagato (1890-1968) and since the early post-war years, their designs have sometimes been polarizing (the phrase “acquired taste” sometimes seen), their angularity often contrasted with the lines of other, notably Pinninfarina and Bertone but unlike many which have over the years folded, Zagato remains active still.  One Zagato design never criticized was his run in 1956 of five Ferrari 250 GT “Tour de France” LWB Berlinettas, memorable also for introducing the signature “Zagato double-bubble roof.  The roof was practical in that it better accommodated taller occupants but it really was a visual trick and a variation on the trick Mercedes-Benz used on the “Pagoda” (W113; 230, 250 & 280 SL; 1963-1971) which they explained by saying “We didn’t lower the roof, we rained the windows”.  The other famous feature (which appeared on only one) was the fetching “Z” shape on the rear pillar, replacing the “Hofmeister kink” used on some others.

1962 Chevrolet Impala “bubbletop” Sport Coupe (left), 1963 Ford Consul Capri (centre) and 1972 BMW 3.0CS (E9, right).

The 1959 Chevrolet quickly came to be nicknamed “bubbletop” and the style spread, both within GM and beyond.  The “bubbletop” reference was to the canopy on aircraft like the P-51D Mustang but was an allusion to the shape, not the materials used; on cars things were done in traditional glass and metal.  Across the Atlantic, Ford in the UK applied the idea to their Consul Capri (1961-1964), a two-door hardtop which the company wanted to be thought of as a “co-respondent's” car (ie the sort of rakish design which would appeal to the sort of chap who slept with other men’s wives, later to be named as “co-respondent” in divorce proceedings).  The Capri was a marketplace failure and the styling was at the time much criticized but it’s now valued as a period piece.  Chevrolet abandoned the look on the full-size cars after 1963 but it was revived for the second series Corvair (1965-1969).  A fine implementation was achieved in the roofline of the BMW E9 (1968-1975) which remains the company’s finest hour.

The bubble shirt and bubble tops.

The bubble skirt (worn by Lindsay Lohan (centre)) is one of those garments which seems never to quite die, although there are many who wish it would.  Once (or for an unfortunate generation, twice) every fashion cycle (typically 10-12 years), the industry does one of its "pushes" and bubble skirts show up in the high street, encouraged sometimes by the odd catwalk appearance; it will happen again.  While the dreaded bubble skirt is easily identifiable, the “bubble top” is less defined but there seem to be two variations: (1) a top with a “bubble skirt-like” appendage gathering unhappily just above the hips (left) and (2) a kind of “boob tube” which, instead of being tightly fitted is topped with an additional layer of material, loosely gathered.  The advantages of the latter (which may be thought of as a “boob bubble”) are it can (1) without any additional devices create the illusion of a fuller bust and (2) allow a strapless bra to be worn, something visually difficult with most boob tubes because the underwear’s outline is obvious under the tight material.

Nerf

Nerf (pronounced nurf)

(1) A device, traditionally metal but of late also rubber or plastic, attached to the front or corners of boats or road vehicles for the purpose of absorbing impacts which would otherwise damage the device to which they’re attached.

(2) A slang term in motorsport which describes the (intentional) use of part of a vehicle to nudge another vehicle off its course; used also to describe the almost full-length protective bars used in some forms of dirt-track (speedway) racing (although the term may have be retrospectively applied, based on the use on hot-rods).

(3) As a trademark, the brand name of a number of toys, often modeled on sports equipment but made of foam rubber or other soft substances.

(4) In video gaming, a slang term for reconfigure an existing character or weapon, rendering it less powerful.

(5) By extension from the original use at the front and rear of 1950s hot rod cars and in motorsport, the name adopted (as nerf bar) for a step to ease entry and exit on pickup trucks or sport utility vehicles (SUV) and known also as step rails, step tubes, step bars or truck steps; also sometimes used to describe the extended foot-rests used on some motorcycles.

(6) As "nerf gun", a toy which fires foam darts, arrows, discs, or foam balls; the class is based on the original "Nerf Blaster" by Hasbro.

Circa 1955: Apparently an invention of US (specifically 1950s Californian hot-rod culture) English, the source of the word being speculative.  The later use, in computer-based gaming, etymologists trace (though there is dissent) from the primitive Indo-European mith- (to exchange, remove) from which Latin gained missilis (that may be thrown (in the plural missilia (presents thrown among the people by the emperors)), source (via the seventeenth century Middle French missile (projectile)) of the English missile ((1) in a military context a self-propelled projectile whose trajectory can sometimes be adjusted after it is launched & (2) any object used as a weapon by being thrown or fired through the air, such as stone, arrow or bullet).  Nerf is a noun & verb, nerfed is a verb & adjective and nerfing is a verb; the noun plural is nerfs.

In the US, nerf bars were often fitted to cars with bumper bars mounted lower than were typically found on domestic vehicles.  What these nerf bars did was provide a low-cost, sacrificial device which would absorb the impact the bodywork would otherwise suffer because the standard bumper would pass under the bumper of whatever was hit in an accident.  On a large scale, the idea was in the 1960s implemented on trucks as the "Mansfield Bar", a (partial) solution to the matter (understood since the 1920s) of cars crashing into the rear of trucks, tending increasingly (as bodywork became lower) to “pass under” the rear of a truck's chassis, meaning it was the passenger compartment (at the windscreen level) which suffered severe damage.  The death toll over the decades was considerable and Jayne Mansfield (1933–1967) the most famous victim, hence the eponymy.  Design rules and regulations began to proliferate only in the late 1960s and remarkably as it must seem in these safety conscious times, in the US it wasn't until the early 1970s that cars were required to be built with standardized bumper-bar heights, front & rear.

The suggested etymology is said to account for the application of nerf to gaming where it means “to cripple, weaken, worsen, deteriorate or debuff” (“debuff” a linguistic novelty attributed to gamers) a character, a weapon, a spell etc.  The idea is apparently derived from the proprietary “Nerf” guns, large-scale (often realized in 1:1) toys which fire extremely soft (and therefore harmless) projectiles (al la missilis from the Latin); the Nerfball in 1970 apparently the first.  It doesn’t however account for the use either in motorsport or on hot-rods but the evidence suggests it was the hot-rod crew who used it first, based on an imperfect echoic, thinking the dirt-track (speedway) drivers using the protective bars running along the outside of the bodywork of their vehicles to nudge other competitors off the track and onto the grass were saying “to nerf” whereas they were actually saying “to turf”.  Because the hot-rods became widely known as part of the novel “youth culture” of the 1950s, the specifics of their slang also sometimes entered the wider vocabulary and the bars of the speedway cars, in an example of back-formation, also became “nerf bars”.

The ultimate hot-rod was the AC Shelby Cobra (1962-1967) of which fewer than a thousand were made, a number exceeded more than fifty-fold by the replica industry which has flourished since the bulge-bodied original was retired in 1967, looming regulations proving just to onerous economically to comply with.  The first Shelby Cobra street cars used nerf bars as attachment points for chrome over-riders but, as a weight-saving measure, the latter were usually removed when the vehicles were used in competition, leaving the raw nerf bars exposed.  The raw look has become popular with customers of the replica versions and, surprisingly, the authorities in some jurisdictions appear to allow them to be registered in this state for street use.

On production vehicles, what are sometimes mistakenly called nerf bars are actually “bumperettes”, cut-down bumpers which in their more dainty iterations were sometimes little more than a decorative allusion to the weight-saving techniques used on genuine competition cars.  The increasing stringent impact regulations imposed during the 1970s ended the trend but modern engineering techniques have allowed designers to pick up the motif in the twenty-first century.

The concept of nerf bars as used on hot-rods existed long before the term became popular and can be found in depictions of Greek and Roman ships from antiquity and remain a common sight today, either as a specifically-designed product or simply as old car-tyres secured to the side of the hull and used especially on vessels such as tug-boats which need often to be maneuvered in close proximity to others.  The correct admiralty term for these is "fender" (ie in the sense of "fending-off" whatever it is the vessel has hit).  Manufactured usually from rubber, foam or plastic, there are also companion products, “marine fenders”, which are larger and permanently attached to docks on quay walls and other berthing structures.  Much larger than those attached to vessels, they're best thought of as big cushions (which often they resemble).  The construct was fend + er (the suffix added to verbs and used to form an agent noun); fend was from the Middle English fenden (defend, fight, prevent), a shortening of defenden (defend), from the Old French deffendre (which endures in modern French as défendre), from the Latin dēfendō (to ward off), the construct being dē- (of, from) +‎ fendō (hit, thrust), from the primitive Indo-European ghen- (strike, kill).

1615–1625: The original use was to describe insects, apparently as a variant of the earlier bugge (beetle), thought to be an alteration of the Middle English budde, from the Old English -budda (beetle) but etymologists are divided on whether the phrase “bug off” (please leave) is related to the undesired presence of insects or was of a distinct origin.  Bug, bugging & debug are nouns & verbs, bugged is a verb & adjective and buggy is a noun & adjective; the noun plural is bugs.  Although “unbug” makes structural sense (ie remove a bug, as opposed to the sense of “debug”), it doesn’t exist whereas forms such as the adjectives unbugged (not bugged) and unbuggable (not able to be bugged) are regarded as standard.

The array of compound forms meaning “someone obsessed with an idea, hobby etc) produced things like “shutterbug” (amateur photographer) & firebug (arsonist) seems first to have emerged in the mid nineteenth century.  The development of this into “a craze or obsession” is thought rapidly to have accelerated in the years just before World War I (1914-1918), again based on the notion of “bitten by the bug” or “caught the bug”, thus the idea of being infected with an unusual enthusiasm for something.  The use to mean a demon, evil spirit, spectre or hobgoblin was first recorded in the mid-fourteenth century and was a clipping of the Middle English bugge (scarecrow, demon, hobgoblin) or uncertain origin although it may have come from the Middle Welsh bwg (ghost; goblin (and linked to the Welsh bwgwl (threat (and earlier “fear”) and the Middle Irish bocanách (supernatural being).  There’s also speculation it may have come from the scary tales told to children which included the idea of a bugge (beetle) at a gigantic scale.  That would have been a fearsome sight and the idea remains fruitful to this day for artists and film-makers needing something frightening in the horror or SF (science fiction) genre.  The use in this sense is long obsolete although the related forms bugbear and bugaboo survive.  Dating from the 1570s, a bugbear was in folklore a kind of “large goblin”, used to inspire fear in children (both as a literary device & for purposes of parental control) and for adults it soon came to mean “a source of dread, resentment or irritation; in modern use it's an “ongoing problem”, a recurring obstacle or adversity or one’s pet peeve.  The obsolete form bugg dates from circa 1620s and was a reference to the troublesome bedbug, the construct a conflation of the middle English bugge (scarecrow, hobgoblin) and the Middle English budde (beetle).  The colloquial sense of “a microbe or germ” dates from 1919, the emergence linked to the misleadingly-named “Spanish flu” pandemic.

Like the rest of us, even scientists, entomologists and zoologists generally probably say “bug” in general conversation, whether about the insects or the viruses and such which cause disease but in writing academic papers they’ll take care to be more precise.  Because to most of us “bugs” can be any of the small, creepy pests which intrude on our lives (some of which are actually helpful in that quietly and unobtrusively they dispose of the really annoying bugs which bite us), the word is casually and interchangeably applied to bees, ants, bees, millipedes, beetles, spiders and anything else resembling an insect.  That use may be reinforced by the idea of the thing “bugging” us by their very presence.  To the professionals however, insects are those organisms in the classification Insecta, a very large class of animals, the members of which have a three-part body, six legs and (usually) two pairs of wings whereas a bug is a member of the order Hemiptera (which in the taxonomic system is within the Insecta class) and includes cicadas, aphids and stink bugs; to emphasize the point, scientists often speak of those in the order Hemiptera as “true bugs”.  The true bugs are those insects with mouthparts adapted for piercing and sucking, contained usually in a beak-shaped structure, a vision agonizingly familiar to anyone who has suffered the company of bedbugs.  That’s why lice are bugs and cockroaches are not but the latter will continue to be called bugs, often with some preceding expletive.

9 September 1947: The engineer's note (with physical evidence) of electronic computing's "first bug".

In computing, where the term “bug” came to be used to describe “glitches, crashes” and such, it has evolved to apply almost exclusively to software issues and even if events are caused by hardware flaws, unless it’s something obvious (small explosions, flame & smoke etc) most users probably assume a fault in some software layer.  The very first documented bug however was an interaction recorded on 9 September 1947 between the natural world and hardware, an engineer’s examination of an early (large) computer revealing an insect had sacrificially landed on one of the circuits, shorting it out and shutting-down the machine.  As proof, the unfortunate moth was taped to the report.  On a larger scale (zoologically rather than the hardware), the problem of small rodents such as mice entering the internals of printers, there to die from various causes (impact injuries, starvation, heat et al) remains not uncommon, resulting sometimes in mechanical damage, sometimes just the implications of decaying flesh.

The idea of a bug as a “defect, flaw, fault or glitch” in a mechanical or electrical device was first recorded in the late 1800s as engineer’s slang, the assumption being they wished to convey the idea of “a small fault” (and thus easily fixed, as opposed to some fundamental mistake which would necessitate a re-design).  Some sources suggest the origin lies with Thomas Edison (1847-1931) who is reported as describing the consequences of an insect “getting into the works”.  Programmers deploy an array of adjectives to "bug" (major, minor, serious, critical & non-critical et al) although between themselves (and certainly when disparaging of the code of others) the most commonly heard phrase is probably “stupid bug”.  The “debugging” (also as de-bugging) process is something with a wide definition but in general it refers to any action or set of actions taken to remove errors.  The name of the debug.exe (originally debug.com) program included with a number of (almost all 16 & 32-bit) operating systems was a little misleading because in addition to fixing things, it could be used for other purposes and is fondly remembered by those who wrote Q&D (quick & dirty) work-arounds which, written in assembler, ran very fast.  The verb debug was first used in 1945 in the sense of “remove the faults from a machine” and by 1964 it appeared in field service manuals documenting the steps to be taken to “remove a concealed microphone”.  Although the origin of the use of “bug” in computing (probably the now most commonly used context) can be traced to 1947, the term wasn’t widely used beyond universities, industry and government sites before the 1960s when the public first began to interact at scale with the implications (including the bugs) of those institutions using computerized processes.  Software (or any machinery) badly afflicted by bugs can be called “buggy”, a re-purposing of the use of an adjective dating from 1714 meaning “a place infested with bugs”.

Some bugs gained notoriety.  In the late 1990s, it wasn’t uncommon for the press to refer to the potential problems of computer code using a two-numeral syntax for years as the “Y2K bug” which was an indication of how wide was the vista of the common understanding of "bug" and one quite reasonable because that was how the consequences would be understood.  A massive testing & rectification effort was undertaken by the industry (and corporations, induced by legislation and the fear of litigation) and with the coming of 1 January 2000 almost nothing strange happened and that may also have been the case had nothing been done but, on the basis of the precautionary principle, it was the right approach.  Of course switching protocols to use four-numeral years did nothing about the Y10K bug but a (possible) problem 8000 years hence would have been of little interest to politicians or corporate boards.  Actually, YxK bugs will re-occur (with decreasing frequency) whenever a digit needs to be added.  The obvious solution is trailing zeros although if one thinks in terms of infinity, it may be that, in the narrow technical sense, such a solution would just create an additional problem although perhaps one of no practical significance.  Because of the way programmers exploit the way computers work, there have since the 1950s been other date (“time” to a computer) related “bugs” and management of these and the minor problems caused has been handled well.  Within the industry the feeling is things like the “year 2029 problem” and “year 2038 problem” will, for most of the planet, be similarly uneventful.

The DOSShell, introduced with PC-DOS 4.0; this was as graphical as DOS got.  The DOSShell was bug-free.

Bugs can also become quirky industry footnotes.  As late as 1987, IBM had intended to release the update of PC-DOS 3.3 as version 3.4, reflecting the corporation’s roadmap of DOS as something of an evolutionary dead-end, doomed ultimately to end up in washing machine controllers and such while the consumer and corporate market would shift to OS/2, the new operating system which offered pre-emptive multi-tasking and access to bigger storage and memory addressing.  However, at that point, both DOS & OS/2 were being co-developed by IBM & Microsoft and agreement was reached to release a version 4 of DOS.  DOS 4 also included a way of accessing larger storage space (through a work-around with a program called share.exe) and more memory (in a way less elegant than the OS/2 approach but it did work, albeit more slowly), both things of great interest to Microsoft because they would increase the appeal of its upcoming Windows 3.0, a graphical shell which ran on top of DOS; unlike OS/2, Windows was exclusive to Microsoft and so was the revenue stream.  Unfortunately, it transpired the memory tricks used by PC-DOS 4.0 were “buggy” when used with some non-IBM hardware and the OS gained a bad reputation from which it would never recover.  By the time the code was fixed, Microsoft was ready to release its own version as MS-DOS 4.0 but, noting all the bad publicity, after a minor updates and some cosmetic revisions, the mainstream release was MS-DOS 4.01.  In the code of the earlier bug-afflicted bits, there is apparently no difference between MS-DOS 4.01 the few existing copies of MS-DOS 4.0.

In idiomatic and other uses, bug has a long history.  By the early twentieth century “bugs” meant “mad; crazy" and by then “bug juice” had been in use for some thirty years, meaning both “propensity of the use of alcoholic drink to induce bad behaviour” and “bad whiskey” (in the sense of a product being of such dubious quality it was effectively a poison).  A slang dictionary from 1811 listed “bug-hunter” as “an upholsterer”, an allusion to the fondness bugs and other small creatures show for sheltering in the dark, concealed parts of furniture.  As early as the 1560s, a “bug-word” was a word or phrase which “irritated or vexed”.  The idea of “bug-eyed” was in use by the early 1870s and that’s thought either to be a humorous mispronunciation of bulge or (as is thought more likely) an allusion to the prominent, protruding eyes of creatures like frogs, the idea being they sat on the body like “a pair of bugs”.  The look became so common in the movies featuring aliens from space that by the early 1950s the acronym BEM (bug-eyed monster) had become part of industry slang.  The correct term for the medical condition of "bulging eyes" is exophthalmos.

To “bug someone” in the sense of “to annoy or irritate” seems not to have been recorded until 1949 and while some suggest the origin of that was in swing music slang, it remains obscure.  The now rare use of “bug off” to mean “to scram, to skedaddle” is documented since 1956 and is of uncertain origin but may be linked to the Korean War (1950-1953) era US Army slang meaning “stage a precipitous retreat”, first used during a military reversal.  The ultimate source was likely the UK, Australian & New Zealand slang “bugger off” (please leave).  The “doodle-bug” was first described in 1865 and was Southern US dialect for a type of beetle.  In 1944, the popular slang for the German Vergeltungswaffen eins (the V-1 (reprisal weapon 1) which was the first cruise missile) was “flying bomb” or “buzz bomb”) but the Royal Air Force (RAF) pilots preferred “doodle-bug”.

The ultimate door-stop for aircraft hangers: Bond Bug 700.

The popularity of three wheeler cars in the UK during the post-war years was a product of cost breakdown.  They were taxed at a much lower rate than conventional four-wheel vehicles, were small and thus economical and could be operated by anyone with only a motorcycle licence.  Most were actually genuine four-seaters and thus an attractive alternative for families and, being purely utilitarian, there were few attempts to introduce elements of style.  The Bond Bug (1970-1974) was an exception in that it was designed to appeal to the youth market with a sporty-looking two-seater using the then popular “wedge-styling” and in its most powerful form it could touch 80 mph (130 km/h), faster than any other three wheeler available.  However, the UK in 1973 introduced a value-added tax (VAT) and this removed many of the financial advantages the three-wheelers.  In an era of rising prosperity, the appeal of the compromise waned and coupled with some problems in the early productions runs, in 1974, after some 2¼ thousand Bugs had been built, the zany little machine was dropped; not even the oil crisis of the time (which had doomed a good number of bigger, thirstier cars) could save it.  Even in its best years it was never all that successful, essentially because it was really a novelty and there were “real” cars available for less money.  Still, the survivors have a following in their niche at the lower end of the collector market.

The business of spying is said to be the “second oldest profession” and even if not literally true, few doubt the synergistic callings of espionage and war are among man’s earliest and most enduring endeavors.  Although the use of “bug” to mean “equip with a concealed microphone” seems not to have been in use until 1946, bugging devices probably go back thousands of years (in a low-tech sort of way) and those known to have been used in Tudor-era England (1485-1603) are representative of the way available stuff was adapted, the most popular being tubular structures which, if pressed against a thin wall (or preferably a door’s keyhole) enabled one to listen to what was being discussed in a closed room.  Bugging began to assume its modern form when messages began to be transmitted over copper wires which could stretch for thousands of miles and the early term for a “phone bug” was “phone tap”, based upon the idea of “tapping into” the line as one might a water pipe.  Bugs (the name picked-up because many of the early devices were small, black and “bug-like”), whether as concealed microphones or phone taps, swiftly became part of the espionage inventory in diplomacy, commerce and crime and as technology evolved, so did the bugging techniques.

Henry Cabot Lodge Jr (1902–1985), US Ambassador to the UN (United Nations) at a May 1960 session of the Security Council, using the Great Seal bug to illustrate the extent of Soviet bugging.  The context was a tu quoque squabble between the Cold War protagonists, following Soviet revelations about the flight-paths of the American's U2 spy planes.  Lodge would be Richard Nixon’s (1913-1994; US president 1969-1974) running mate in that year's presidential election.     

A classic bug of High Cold War was the Great Seal bug, (known to the security services as the thing), a Soviet designed and built concealed listening device which was so effective because it used passive transmission protocols for its audio signal, thereby rendering it invisible to conventional “bug-detection” techniques.  The bug was concealed inside large, carved wooden rendition of the US Great Seal which, in 1945, the Kremlin presented as a “gift of friendship” to the US Ambassador to the USSR Averell Harriman (1891-1986); in a nice touch, it was a group of Russian school children who handed over the carving.  Sitting in the ambassador’s Moscow office for some seven years, it was a masterpiece of its time because (1) being activated only when exposed to a low-energy radio signal which Soviet spies would transmit from outside, when subjected to a US “bug detection” it would appear to be a piece of wood and (2) as it needed no form of battery or other power supply (and indeed, no maintenance at all), its lifespan was indefinite.  Had it not by chance been discovered by a communications officer at the nearby British embassy who happened to be tuned to the same frequency while the Soviets were sending their signal, it may well have remained in place for decades.  Essentially, the principles of the Great Seal bug were those used in modern radio-frequency identification (RFID) systems.
