Youse

Youse (pronounced yooz, yuhz or yiz (in ascending order of boganess))

A non-standard pronoun; an alternative form of “you” (usually when addressing or referring to two or more people).

1876: A dialectal inflection of you, first noted as being used in plural senses but also as a simple alternative to you; sometimes spelled yous, mostly in the US.  Some sources cite 1893 as the first known citation but most reference 1876 and the other forms, y'all & you-uns, are US variations, found mostly south of the Mason-Dixon Line.  Although undocumented, use likely dates from the early days of English.  Urban Dictionary notes the existence of "you'se", apparently an alternative to "you're" (their example of use was "You'se a bitch!" so it may be handy in the right company).  

As a plural, it’s most prevalent in (northern) England, Scotland, Ireland, Australia, New Zealand, South Africa, northern Nova Scotia, parts of Ontario, the north-eastern United States (especially areas like Boston with high rates of Irish immigration) and in Mexican-American communities in the southwest.  It’s also widely used in Scouse.  As a singular, it’s most common in Philadelphia, New York, Boston and in working class Italian-American communities.  Like most of the English-speaking world, in Australia, youse is a class-identifier and thought exclusively bogan, which, for those for whom English isn’t a first language, is a little unfair because (1) it would be a useful word if acceptable and (2) for later adopters of English it must seem strange youse is wrong because, as a plural formation, technically, it follows the rules.

Descriptive vs Prescriptive Dictionaries

Structural linguistics can be either descriptive or prescriptive, the former documenting how words are used by the folk using them, the latter a codification of the rules (spelling, pronunciation, grammar etc) which define how language should be used.  Samuel Johnson's (1709-1784) A Dictionary of the English Language (1755) wasn’t the first dictionary but was one of the most influential and it’s a hybrid, full of amusing and idiosyncratic entries as well as many errors but it all reflected the author’s understanding of the language as it existed; what was right and wrong as well as what was actually done.

In the US, "youse" is a regionalism and the New York Times claimed that when referring to groups of two or more, other forms were anyway more popular in different parts of the country.  It does however seem to appear disproportionately in US film & television, presumably because it works well as an ethnic & class identifier.  On the "Streets of America" in Disney's Hollywood Studios, there are many façades but one structure which is real is Youse Guys Moychindice, a souvenir kiosk in the style of those still seen in films set in New York City and stereotypically run by Italian & Irish-Americans.  Youse Guys Moychindice stocks a variety of snacks, hats, cups, plush toys and assorted gifts.

As the rules of English became increasingly standardised, dictionaries tended to being prescriptive (OED, Cambridge, Webster’s et al) texts which were lists of correct words and their meanings, lexicons of that which conformed to accepted rules.  Then, later, there were dictionaries of slang which documented English as it was actually spoken with its inventions, malapropisms, the often inexplicable and the frequently ephemeral; these were the descriptive works.  As dictionaries either moved or replicated their print editions online, the distinctions were maintained and refined.  Merriam-Webster for example publishes print editions which include only formal, correct English whereas the dynamic online version is inclusive or promiscuous, depending on one’s view.

English anyway has no centralised authority which defines right and wrong as the Académie française and Goethe-Institut respectively provide for French and German, the evolution of English being organic.  So, if a word like youse is either to endure as a bogan niche or gain the critical mass of middle-class acceptance will depend entirely on users of the language and eventually, dictionaries will reflect this.  Use and meanings in English do change; there are words now contronyms, things which in modern use, now mean the opposite of their classical origins.

Serendipity

Serendipity (pronounced ser-uhn-dip-i-tee)

(1) The faculty of making fortunate discoveries by accident; a combination of events which have come together by chance to make a surprisingly good or wonderful outcome.

(2) Luck, good fortune.

(3) As the serendipity berry (Dioscoreophyllum volkensii), a tropical dioecious rainforest vine in the family Menispermaceae, native to tropical Africa from Sierra Leone east to Eritrea, and south to Angola and Mozambique.

1754: The construct was Serendip + -ity.  The proper noun Serendip (Serendib the alternative form) was an archaic name for the island of Ceylon (सिंहल (siṃhala (Sri Lanka”) after 1972 from द्वीप (dvīpa) (island)), from the Arabic سَرَنْدِيب‎ (sarandīb), from the Persian سرندیپ‎ (sarandip), from the Prakrit sīhaladīva & Sanskrit सिंहलद्वीप (siṃhaladvīpa (literally “island of the Sinhala people”)).  The –ity suffix was from the French -ité, from the Middle French -ité, from the Old French –ete & -eteit (-ity), from the Latin -itātem, from -itās, from the primitive Indo-European suffix –it.  It was cognate with the Gothic –iþa (-th), the Old High German -ida (-th) and the Old English -þo, -þu & -þ (-th).  It was used to form nouns from adjectives (especially abstract nouns), thus most often associated with nouns referring to the state, property, or quality of conforming to the adjective's description.

Serendipity berries, one of the “miracle berries”.

The serendipity berry is noted as a source of monellin, an intensely sweet protein and if chewed, alters the perception of taste to make tart, acidic or bitter food taste sweet.  Pills containing synthesized monellin are sold as “miracle fruit tablets” for this purpose (a lemon eaten after sucking on one of these tablets quite a revelation) and as “miracle fruit”, serendipity and related berries are widely used in African folk medicine although there’s scant evidence for their efficacy as a treatment for the many diseases they’re said to cure.  Words with a similar meaning include fluke, happenstance, blessing, break and luck but serendipity carries the particular sense of something very useful and wholly unexpected being the result while The phrases “Murphy's law” & “perfect storm” are close to being antonyms.  In science and industry, serendipity has played a part in the discovery or development of vaccination, insulin to treat diabetes, penicillin, quinine, Viagra, x-rays, radioactivity, pulsars, cosmic microwave background radiation, Teflon, vulcanized rubber, microwave ovens, Velcro and 3M's (originally Minnesota Mining & Manufacturing) post-it notes (though it seems its part in the invention of stainless steel may be a myth).  Serendipity & serendipitist are nouns, serendipitously is an adverb and serendipitous is an adjective; the noun plural is serendipities.  Serendipiter & serendipper are non-standard noun forms adopted in popular culture.

Serendipity was in 1754 coined by the English Whig politician & author writer Horace Walpole (1717–1797), derived from the fairy tale The Three Princes of Serendip, the three, Walpole noted, “always making discoveries, by accidents and sagacity, of things which they were not in quest of”.  The Three Princes of Serendip was an English version of Peregrinaggio di tre giovani figliuoli del re di Serendippo, printed in 1557 by Venetian publisher Michele Tramezzino (1526-1571), the text said to have been the work of a Cristoforo Armeno who had translated the Persian fairy tale into Italian, adapting Book One of Amir Khusrau's Hasht-Bihisht (1302). The story was translated into French before the first English edition was published and Voltaire (François-Marie Arouet, 1694–1778) used the tale in his 1797 novella Zadig ou la Destinée (Zadig or The Book of Fate), an intriguing fusion of fiction and philosophy which influenced systematic science, the evolution of creative writing about crime and even horror stories.

Portrait of Horace Walpole (1728), aged ten by William Hogarth (1697-1784) in gilt frame, Strawberry Hill House, Twickenham.  He was the youngest son of Sir Robert Walpole (1676-1745), the Whig politician who between 1721-1742 served as first lord of the Treasury, chancellor of the exchequer and leader of the House of Commons; by virtue of this, he came to be recognized as Britain's first prime-minister.

Walpole used serendipity first in a letter (dated 28 January 1754) he wrote to Florence-based British diplomat Sir Horace Mann (1706–1786) but which seems not to have been published until 1833, the new word remaining almost unnoticed until the 1870s when there was a brief spike; it was in the early-mid twentieth century it became popular and until then it was rare to find a dictionary entry although the adjective serendipitous appeared as early as 1914.  Walpole was compelled to coin serendipity to illustrate his delighted surprise at finding a detail in a painting of Bianca Cappello (1548–1587 and latterly of the clan Medici) by Giorgio Vasari (1511-1574).  The charm of the word is such that it’s been borrowed, unaltered, by many languages and it frequently appears in "favorite word" or "words of the year" lists.

Portrait of Bianca Cappello, Second Wife of Francesco I de' Medici (circa 1580), fresco by Alessandro Allori (1535-1607), Galleria degli Uffizi, Firenze.

The twenty-two-year-old Walpole fell under the charm of the long dead Bianca Cappello while staying in Florence during his grand tour of the continent.  Besotted by the portrait of the peach-skinned Venetian beauty which hung in the Casa Vitelli, it's not clear what immediately drew his eye but a diary note by the French writer Montaigne (1533–1592), who in 1580 had the pleasure of meeting her, might provide a hint: “...belle à l’opinion italienne, un visage agréable et imperieux, le corsage gros, et de tetins à leur fouhait” ("...according to the Italians she is beautiful.  She has an agreeable and imposing face, and large breasts, the way they like them here…").  He confided his passion to Mann who around 1753 purchased the work, sending it to his friend who had by then returned to England, his cover letter including the revelatory “It is an old acquaintance of yours, and once much admired by you... it is the portrait you so often went to see in Casa Vitelli of Bianca Capello… to which, as your proxy, I have made love to for a long while… It has hung in my bedchamber and reproached me indeed of infidelity, in depriving you of what I originally designed for you”.  These days, such things are called objectum sexuality or fictosexualism but in the eighteenth century it was just something the English aristocracy did.

Whatever other pleasures the oil on canvas bought him, Walpole must also have devoted some attention to detail for he would soon write back to Mann: “I must tell you a critical discovery of mine a propos in a book of Venetian arms.  There are two coats of Capello… on one of them is added a fleu de luce on a blue ball, which I am persuaded was given to the family by the Grand Duke” (of Medici who was Bianca's second husband (who may have murdered the first)).  Much pleased at having stumbled upon this link between the two families in a book of Venetian heraldry he happened at the time to be reading in the search for suitable emblems with which to adorn the painting's frame, he told his dear friend: “This discovery indeed is almost of that kind which I call SERENDIPITY”.

Digisexual & Fictosexual

Digisexual (pronounced dij-i-sek-shoo-uhl (U) or dij-I-seks-yoo-l (non-U))

(1) A person who is sexually attracted to robots or other technologically-mediated forms of sexuality.

(2) The predilection to or the practice of digisexuality.

Circa 2017: The construct was digi(tal)- +‎ -sexual.  The digi- prefix was from the Latin digitālis, the construct being digitus (finger, toe) + -alis (-al), the third-declension two-termination suffix (neuter -āle) used to form adjectives of relationship from nouns or numerals).  Originally vested with the meanings “having to do with digits (fingers or toes)” & performed with a finger etc, it came to be applied to computing in the sense of “property of representing values as discrete, often binary, numbers rather than a continuous spectrum”, the link being the used of base-10 mathematics and the ten (fingers & thumbs) digits of a human’s hands.

Sexual was from Latin sexuālis, from sexus (sex), from the Proto-Italic seksus, from the primitive Indo-European séksus, from sek- (to cut) (thus the sense of “section, division”, the binary division into male and female).  The generalized meaning “arising from the fact of being male or female; pertaining to sex or gender, or to the social relations between the sexes” dates from the seventeenth century, the specific use in the biological sciences (capable of sexual reproduction; sexed, sexuate) not current until the mid-1800s although the familiar sense “pertaining to sexual intercourse or other intimate physical contact was common a century earlier.  The meaning “pertaining to the female sex” is noted by etymologists as enjoying currency only between the seventeenth & nineteenth century and being obsolete but a specific sense did survive as a literary device, the novelist Anaïs Nin (1903–1977) often using the phrase “my sex” to refer to her own genitals.

In some sense, what is now understood as digisexuality may have been around for a while but the neologism was coined in 2017 (there are references to some use of the term in 2014) to describe people for whom the primary and preferred sexual identity and experience of sex would be mediated by or conducted with some form of technology.  Interestingly, the researchers who authored the paper (Sexual and Relationship Therapy 32(1):1-11 (November 2017) by Neil McArthur & Markie L C Twist (Blumer)) positioned their concept as predictive, noting that while “radical new sexual technologies” which accommodated what they termed “digisexualities” already existed, it was advances in the technology which would see a growth in the numbers who would come to identify themselves as digisexuals, those whose primary sexual identity comes through the use of technology.  In one sense it was just an aspect of applied technology, much of the hardware and software a specific adaptation of developments in robotics for fields as diverse as the military, production line assembly and aged care but the social, legal, and ethical implications were many, including the need for clinicians working in mental health to become familiar with the challenges and benefits associated with the adoption of such sexual technologies.

Legal issues involving the representation of some of the machinery recently produced have been publicized by law enforcement bodies but one ethical matter which may in the future emerge is that of consent.  A Google software engineer who describes himself as a “Christian mystic” was recently placed on administrative leave after claiming LaMDA (language model for dialogue applications, a Google artificial intelligence (AI) chatbot on which he was working) had become sentient.  The engineer’s posts on the matter indicated he used sentient in one of its more modern senses (possessing human-like awareness and intelligence) rather than the traditional "experiencing sensation, thought, or feeling; able consciously to perceive through the use of sense faculties; self-aware”.  LaMDA is computer code running on a distributed machine made from silicon, metals, plastics and such.  The code was written by humans and, even if some was self-generated by the machine, the parameters within which that’s possible were also human-defined and the consensus remains that such an agglomeration cannot become sentient; there’s no reason why it could not attain a capability to appear sentient to those with which it interacts but that’s different from being sentient.  It’s a convincing emulation which many computer scientists have for some time predicted is inevitable although not all agree all people can be fooled all of the time.

Digi & ficto sexuality can interact with objectum sexuality.  Individuals may form relationships with non-living devices or concepts but it's not impossible a court may one day find such things have certain enforceable rights although given the real-world implications attached to individuals interacting with AI bots, legal developments are more likely to focus on protecting the users (in a sense, "from themselves").

A digisexual relationship with something like LaMDA, although something which may be a matter of concern for some reasons, seems not to raise the issue of consent; LaMDA is a machine and can only appear to grant or withhold consent although there will be those who find disturbing the notion of someone performing a digisexual act on a machine which has said no.  Whether this is any worse than first-person shooter games isn’t clear but it’s certainly something which will attract more attention, sex seemingly more upsetting than violence.  However, there’s much interest in bio-computing (computers which use biological molecules (DNA, proteins etc)) to augment the traditional silicon-based platform.  At that point, the machine becomes in some way alive with the possibilities that implies and, although such a device remains hypothetical, it may be it become possible to create a machine with a brain (as conventionally understood).  At that point the right of a machine to say no presumably might become an issue and one which courts may have to discuss.  While a US court recently ruled a elephant can’t at law be a person a New Zealand court decided personhood could be conferred on a river.  How a court would deal with a machine which claims to have been violated is not predictable and may vary between jurisdictions.

Fictosexual (pronounced fik-toh-sek-shoo-uhl (U) or fik-toh-seks-yoo-l (non-U))

An identity for someone for whom the primary form of sexual attraction is fictional characters.

Circa 2014: The construct was fict(i)o(n) + sexual.  Ficto was a clipping of fiction, from the Middle English ficcioun, from the Old French ficcion (dissimulation, ruse, invention), from the Latin fictiō (a making, fashioning, a feigning, a rhetorical or legal fiction), from fingō (to form, mold, shape, devise, feign). It displaced the native Old English lēasspell (literally “false story”).

Sexual was from Latin sexuālis, from sexus (sex), from the Proto-Italic seksus, from the primitive Indo-European séksus, from sek- (to cut) (thus the sense of “section, division”, the binary division into male and female).  The generalized meaning “arising from the fact of being male or female; pertaining to sex or gender, or to the social relations between the sexes” dates from the seventeenth century, the specific use in the biological sciences (capable of sexual reproduction; sexed, sexuate) not current until the mid-1800s although the familiar sense “pertaining to sexual intercourse or other intimate physical contact was common a century earlier.

Flag of the fictosexual.

The black and grey stripes represent the lack of attraction towards non-fictional individuals, the purple stripe represents sexual attraction and the asexual spectrum, the black circle represents a portal to the fictional world in question, and pink represents attraction to fictional characters.

Fictosexuality (fictoromance & fictophilia are related) is an umbrella term for anyone who experience sexual attraction toward fictional characters, a general type of fictional characters, or whose sexuality is influenced by fictional characters.  As a noted behavior in mental illnesses with a delusional component, there’s doubtless a long history but the word seems first to have come into use circa 2014 but none of the documents which discuss fictosexuality appear to address the technical point of the status of the fictional depiction of a historic character.  Like digisexuality, fictosexuality is not dissimilar to Objectum sexuality, a condition in which people have a primary interest in objects.  The categories included under the fictosexual umbrella are not mutually exclusive and definitional overlap is noted:

Animesexuality: An exclusive attraction to anime.

Cartosexual: An attraction to cartoon or comic characters.

Booklosexual: An attraction to the characters in novels.

Visualnovelsexual: An attraction to the characters in visual novels.

Gamosexual: An attraction to the characters in video games.

Imagisexual: An attraction to fictional characters one can never see (book, audio characters etc).

Inreasexual: An attraction to characters from live-active genres.

OCsexual: An attraction to original characters.

Teratosexual: An attraction to monster-related characters.

Tobusexual: An attraction to vampire-related characters.

Spectrosexual: An attraction to ghost-related characters.

Nekosexual: An attraction to neko-related characters (usually in anime).

Anuafsexual: An attraction to other animal and human hybrid characters.

Multifictino: A mix of exclusive fictional attraction.

Aliussexual: An attraction for fictionkin; the attraction to fictional characters from their source.

Fictosexual Akihiko Kondo san with Hatsune Miku san doll.

Advances in materials, computer processing and software mean that fictosexuals can now allow their love to manifest digisexually though such relationships are not without their ups and downs.  Fictosexual Akihiko Kondo san (b 1984), a employee of Tokyo’s local government (and self-described otaku (one who is obsessed with something, especially Manga or anime)), had for ten years maintained a fictosexual relationship with Hatsune Miku san, depicted in pop culture as a 16-year-old with turquoise hair before their (unofficial) wedding ceremony in 2018.  The wedding was, by Japanese standards, a modest affair on which Kondo san spent about 2 million yen (US$14,750) but his family, not approving of the computer-synthesized, pop singer bride, choose not to attend although several dozen others, including other fictosexuals, witnessed the ceremony.  Unfortunately, although still deeply in love with Miku san, he finds himself now unable to communicate with his wife because support for the Gatebox (a US$1000 device which enabled owners interact with holograms) has been dropped.  It was through the Gatebox that in 2017 Kondo san proposed marriage and after he popped the question, she replied "I hope you'll cherish me."

Miku san was created as a synthesised voice using Yamaha’s Vocaloid technology and entered mainstream media as a fictionalised human character in Manga, anime series and video games.  Her appeal cut across many demographics and proved cross-cultural, joining Lady Gaga on her 2014 Artpop Ball tour.  Kondo san first became acquainted with Miku san in 2008 while suffering depression after being bullied at work and the presence in his life proved therapeutic, bring him acceptance that human relationships were not right for him and spending days at a time in his room watching Miku san videos saw the relationship blossom.  Since oral communication became impossible, Kondo san carries with him a life-sized Miku san doll.

Circa 1200: From the Middle English deltha from the Latin delta from the Ancient Greek δέλτα (délta), from the Phoenician dalet & daleth (tent door).  It was akin to the Hebrew dāleth.  It was the fourth letter of the Greek alphabet (equivalent to the Modern English D) and was shaped like a triangle (Δ).  The sense of a delta being a "triangular island or alluvial tract between the diverging branches of the mouth of a great river" is because the Ancient Greek writer Herodotus (circa 484–circa 425 BC) used it to describe the mouth of the Nile River (now known as the Nile Delta).  That was picked up in English during the 1550s and applied to other river mouths (often of quite different shapes) by 1790.  The related forms are deltaic and deltification.  In pre-modern medicine, the deltoid muscle (the large muscle of the shoulder; triangular, resembling the Greek letter delta) was described in 1758, the name from the Ancient Greek deltoeides (triangular, literally "shaped like the letter delta).  In modern use, the "deltoid muscle" gained the short-form “delts” in 1977.  The related form is deltoidal.

The delta-wing

Gloster Javelin (1951-1967).  The first twin-engined delta-wing in service, the Javelin was the UK’s long-term solution to its need for an all-weather interceptor, the post-war technology gap until then filled by the stop-gap Gloster Meteor and that most improbable cold-war fighter, the de Havilland Mosquito.  The Javelin was the last aircraft to bear the Gloster name, the company absorbed into the morass created by the mergers, acquisitions and nationalization that befell British industry between Attlee and Thatcher. 

In aviation, the delta shape pre-dated aircraft by centuries, triangular stabilizing fins for rockets described in the sixteenth and seventeenth centuries and the first lifting wing in delta form patented in 1867 for use by a dart-shaped, rocket-propelled airplane.  However, although there were prototypes and much theoretical work was done during the first half of the twentieth century, it wasn’t until the late-1940s when jet propulsion made possible high-speed subsonic and supersonic flight that it was possible to build airframes which could take advantages of the delta-wing’s unique properties.

Lockheed SR-71 Blackbird (1963-1999).  A product of Lockheed’s Skunk Works, although in development as a high-altitude interceptor since 1959, the US government didn’t admit the SR-71 existed until 1964 and decided ultimately to use it for reconnaissance and research into supersonic flight.  The SR-71 in 1976 set the world record for the fastest flight by an air-breathing manned aircraft and the mark still stands.

The delta form offers structural advantages and aerodynamic characteristics suited to the fluid dynamics of airflow in supersonic conditions.  To suit different applications, design variations have evolved, with and without additional stabilizing surfaces.  The long root chord of the delta wing and minimal structure outboard is inherently structurally efficient, able to be built stronger and stiffer yet lighter than a swept wing of equivalent lifting capability.  It’s thus simple and relatively inexpensive to build.

Avro Vulcan (1956-1984).

Until the UK adopted the submarine-launched Polaris missile system, the Vulcan was the platform for the UK’s independent nuclear deterrent and it remained in service long enough to be deployed for its only combat mission, a flight of five aircraft used for (conventional bombing) missions during the 1982 Falklands War.  Each aircraft flew almost 4000 miles  (6,500 km) from Ascension Island, Victor tankers used for the air-to-air refueling, almost 1.1 million gallons (5 million litres ) of fuel burned each mission.

The long root chord also allows a deeper structure for a given aerofoil section, providing more internal volume for fuel and other storage without a significant increase in drag although, on supersonic designs, designers often take the opportunity to use a thinner aerofoil instead, thereby further reducing drag.  Usefully, the large root chord also provides a large surface area which assists in reducing the minimum speed; a low landing speed being a design objective in most military and civil applications.  Delta wings can be designed to induce vortex lift, so flow separation can be turned into a means of increasing lift and the whole structure is naturally stable in pitch, therefore not requiring a separate tail surface.

Aérospatiale/BAC Concorde (1969-2003).

The Anglo-French supersonic passenger jet operated commercially between 1976-2003.  Flying at twice the speed of sound and carrying up to 128 passengers, it was the longest lasting of its time, the Soviet Tupolev Tu-144 in passenger service only for a few years during the 1970s after which it operated both as a freighter and a research platform and the American SST never progressed beyond engineering mock-ups.  The Americans worked out the economics were never going to make sense; the Soviets had a different relationship to money and the Concorde lasted as long as it did only because the French & British governments wrote-off the development costs.

There are drawbacks.  The large wing area creates more viscous drag for the same amount of lift compared to a high aspect ratio wing; swept wings have a better lift-to-drag ratio than deltas.  Also, high-lift devices like fowler flaps are hard to integrate into delta wings with the rearward location of the trailing edge producing intolerable pitching moments when such flaps would be deflected.  In short, delta wings are superior only in supersonic flight; their best known design probably the Anglo-French Concorde.

Lindsay Lohan in delta skirts.

A delta skirt is characterized by its triangular shape, an allusion to the Greek letter delta (Δ); almost always, a delta skirt is fitted at the waist, flaring out towards the hem, creating the triangular silhouette.  The concept is adaptable and can be made from just about any fabric, the most popular including cotton, taffeta, silk and a variety of other synthetics.  Delta skirts tend to be shorter because to produce the triangular effect as length increases either some sort of internal structure is required or additional material needs to be used, increasing bulk and weight.  Although most associated with younger women, they have been adopted by a number sub-sets from the anime aesthetic, Goths and bohemians to hippies.

Skunk

Skunk (pronounced skuhngk)

(1) Any of various American musteline mammals (of the weasel family) of the subfamily Mephitinae, especially the Mephitis mephitis (striped skunk), typically having a black and coat with a white, V-shaped stripe on the back and a bushy tail; infamous for the noxious smelling fluid sprayed from two musk glands (anal gland) at the base of the tail when alarmed or attacked

(2) In slang, a most contemptible person; a cheat, knave, scoundrel or stinker.

(3) In slang, anything very bad or a failure; something not a total failure yet with still badly flawed can be described as “skunky” although, in the way of such things, sub-sets of youth have repurposed “skunky” to mean “very good; highly regarded; most satisfactory” (al la the earlier inversion of “filth”), possibly under the influence of the famously potent strain of weed.

(4) In US Navy slang, an unidentified ship or target.

(5) In the slang of drug-users, a strain of Cannabis sativa & Cannabis indica with high levels of tetrahydrocannabinol (THC) (exceeding those of typical hashish), noted for its exceptionally powerful psychoactive properties (also as skunkweed, the name derived from its highly aromatic properties).

(6) In the slang of certain (mostly North American) sports, to defeat thoroughly in a game, especially when the opponent has been prevented from scoring.

(7) In the game of cribbage, a win by 30 or more points (a double skunk 60 or more, a triple skunk 90 or more).

(8) In brewing, of beer, to spoil.

(9) In popular culture, a person whose lifestyle (or as it’s representing in their fashion choices) is a hybrid of the skinhead and punk sub-culture, the construct being sk(inhead) + p(unk).

1625–1630: An early Americanism, described as the Massachusett reflex of the southern New England region Proto-Algonquian šeka·kwa, the construct being šek- (to urinate) + -a·kw (a fox, a fox-like creature); a similar form was noted as the Abnaki segākw, segôgw & segonku (he who squirts urinates).  The first application of the verb was in 1831 when it was used in sport to mean “to completely defeat; to prevent from scoring” and it was used as an insult as early as 1841.  In botany, a local cabbage which gave of a strongly pungent odor when bruised was in 1751 nicknamed skunk-cabbage, having been known as skunkweed since 1738 (botanically unrelated to the later use in drug culture although the etymological influence was similar).

Skunk hair.

The term “skunk hair” originally described a thick blonde highlight applied to dark hair but it’s now used of any two-tone combination (and strictly speaking, beyond two-color schemes it becomes a variegation). Skunk hair is derided by many who treat it as a class-identifier, associating it with those in lower socio-economic demographics, the folk who used to be labelled "not of the better classes".  However, it offers real advantages over other color-changes in that it's possible to design one to accommodate re-growth, something frankly impossible with conventional styles which almost always require maintenance and for true obsessives than can be even weekly.  While it's true there is a genuine "dark roots" aesthetic which on the right subject can be truly stunning, they're a rare breed so it's a niche market few choose to inhabit.  By contrast, a properly executed skunk can last for months.

Czech, Danish, German, Norwegian, Swedish and Slovak all adopted the English spelling, other variations including the Finnish skunkki, the French skunks, the Icelandic skunkur, the Japanese: スカンク (sukanku) and the Russian скунс (skuns).  In idiomatic use, the phrase “as welcome as a skunk at a garden party” refers to someone badly behaved who is unwelcome and actively avoided, the analogy essentially literal.  By contrast, “drunk as a skunk” means “highly inebriated” (also “skunked” in the vernacular) and belongs to a class of phrases which make no apparent sense and endure only because of their memorable rhyme although “drunk as a monk” may have come from empirical observation.  Usefully, in polite society, most are acceptable in a way the rhyming “drunk as a cunt” is not.  Skunk and skunks are nouns & verbs, skunking is a verb, skunked is an adjective & verb, skunky & skunkish are adjectives; the noun plural is skunks or (especially collectively) skunk.  The adverb skunkily is a non-standard form and the verb skunkify appears exclusive to drug and related cultures.

Skunkworks

A favored term in industries such as motorsport, aviation, defense, aerospace and ICT, a skunkworks is a research & development (R&D) facility within a large organization which exists to pursue special or urgent projects which can’t conveniently be pursued within the normal structures.  A skunkworks was originally a distinct physical space but latterly it’s been used also to describe concepts or projects and skunkworks can be either ad-hoc creations which are dissolved when their purpose has been fulfilled or they can evolve into permanent institutions.  One of the attractions of the skunkworks concept is that, properly implemented, it operates without the apparently inevitable bureaucracy which evolves in large corporations, stifling and suppressing new ideas.  In a skunkworks, the only administrative structures which exist are there directly to handle the needs of the project, unlike corporate bureaucracies which rather than being a means to an end, tend to become an impediment to the means.

The origin of the term dates from 1943 when the Lockheed Aircraft Corporation needed urgently to develop a jet-engined pursuit (fighter) aircraft to counter the imminent threat intelligence suggested the allied air forces would soon face from German jet-fighters.  With war production operating at high-intensity, Lockheed’s factories were operating at 100% capacity and thus no space was available for the project so somewhere had to be found.  The details of quite what happened next have become the stuff of industry myth & legend but according to Lockheed-Martin’s official history, a large circus tent was rented and erected next to the closest available space which turned out to be adjacent to a processing facility which used processes emitting a strong odor.  These wafted over, permeating the tent and one of the engineers recalled the newspaper comic strip, "Li'l Abner," in which there was a running joke about a mysterious and malodorous place deep in the forest called the "Skonk Works" where a strong drink was brewed from skunks, old shoes and other strange ingredients.  One day, the engineer answered the telephone by saying "Skonk Works” and, in the way Chinese whispers work, his fellow employees decided it was the punchier “skunk works”, the name adopted by Lockheed as the official pseudonym for their Advanced Development Projects (ADP) division (now Advanced Development Programs).  There are variations of the story including which omits any mention of a tent, suggesting the ADP began in the mot-balled 3G distillery which still reeked with the smells of making bourbon but Lockheed-Martin has published a photograph of a prototype aircraft nose-cone with the tent in the background.

Lockheed P-80 Shooting Star.

The Lockheed P-80 Shooting Star was the first skunkworks project although the team did undertake some work on the P-38 Lightning, first flown in 1939.  The first P-80 was built in a remarkable 147 days which, even given the urgency of wartime production which tended to compress many development programs, did seem to vindicate the skunkworks concept.  The P-80 reflected the thinking of the time and essentially optimized the airframe of a piston-engined fighter around a jet engine.  In that sense it was a developmental cul-de-sac and future directions would be set by the German’s Messerschmitt 262, all designers influenced by the swept-wings and other aerodynamic enhancements which would define the next generation of fighters.  However, the P80’s design was fundamentally sound, in 1946 setting a new world speed record of 623.8 mph (1003.8 km/h) and versions were still used as front-line fighters in the Korean War (1950-1953) although the unexpected appearance in the skies of Russian-built Mikoyan-Gurevich MiG-15s (NATO reporting name: Fagot) saw the US rush to send squadrons of North American F86 Sabres to match the swing-wing threat.  However, some overseas customers used them as fighters as late as 1974 and so versatile did the platform prove that it continued to be developed in a number of roles including reconnaissance, the US military maintaining a fleet as jet-trainers until well into the 1990s.

Other skunkworks projects of note include the U-2 spy plane which played a notable role during the Cold War, the F-104 Starfighter which earned two nicknames (“the manned missile” & “the widow maker”; a brace which may be thought of as cause and effect), the high-speed, high-altitude SR-71 Blackbird which in the 1960s set records which stand today and the F-22 Raptor, thirty-odd years on still the world’s most capable short-range interceptor which would have been produced in much greater numbers had not the USSR dissolved, ending the notion of dog-fights over Berlin being part of the Pentagon’s war-planning.  Much of their work appears now to be devoted to hypersonic (Mach 5 (5 x the speed of sound and beyond)) unmanned aerial vehicles (which should be called "UAVs", the common moniker "drone" not appropriate for these)) platforms for one purpose and another.  Most of the projects are thus far still vaporware although there have been notable advances in systems and specific components but the most dramatic (and best publicized), the SR-72 seems unlike to proceed even to the prototype stage although the speculated shape does suggest the engineers who ran the numbers on the Concorde's wind-tunnel sessions in the 1960s did their sums correctly.  Whatever form of hypersonic UAV eventually does emerge from the skunkworks, it will be armed with hypersonic missiles, a necessity because if existing missiles were used, the thing would shoot itself down.
