Twat

The English word twat is a vulgarism which literally means the vulva or vagina, and is used figuratively as a derogatory epithet. In British English the epithet denotes an obnoxious or stupid person of either sex, whereas in American English it is rarer and usually applied to a woman. In Britain the usual current pronunciation is (rhyming with "hat"); the older pronunciation, still usual in the United States, is (rhyming with "hot" or "squat"), reflected in the former variant spelling twot. The literal sense is first attested in 1656, the epithet in the 1930s. The word's etymology is uncertain. The "American Heritage Dictionary" suggests a conjectural Old English word "*thwāt", "a cut", cognate with Old Norse "þveit" ("thveit"). Jonathon Green suggests a connection with "twitchel", a dialect term for a narrow passage.
19th century.
Robert Browning famously misused the term in his 1841 poem "Pippa Passes":
Frederick J. Furnivall wrote to ask Browning what he meant by "twat"; Browning replied that as a youth he had encountered the word in a volume of broadsides and inferred it to be an item of nun's clothing akin to a wimple. The relevant lines are from "Vanity of Vanities", a 1660 attack on Henry Vane the Younger which includes an anti-Catholic joke:
Melissa Mohr suggests few Victorians knew the word, given that "none of the twenty-three or so Victorian editions" of Browning's poem omit it. An 1868 query to "Notes and Queries" asked what the word in the poem meant; the only published reply was, "Twat is good Somersetshire dialect for a toad=twoad=twat". A footnote in William James Rolfe and Heloise Hersey's 1886 "Select Poems of Robert Browning" summarised his reply to Furnivall with the additional comment, ""Twat" is in no dictionary"; H. W. Fay noted in 1888 in "The Academy" that the word was in fact in Thomas Wright's 1857 "Dictionary of Obsolete and Provincial English", and said Browning, Furnivall and Rolfe had all made a "distressing blunder". The 1894 reprint of "Select Poems" replaced the comment with "Browning would not have used the word if he had known its meaning". In 1911 Basil Lanneau Gildersleeve alluded to "a notorious word which smirches the skirt of Pippa Passes".
Browning's error posed a dilemma for many pre-1960s lexicographers, who excluded words deemed obscene but aspired to include all words used by major writers like Browning. The 1890 "Century Dictionary" included the correct definition, labelled "vulgar", and noted Browning's "supposition" of its meaning. In 1934 "Webster's Second New International Dictionary"'s entry for "twat" read: "Some part of a nun's garb. "Erron. Browning"". The "Oxford English Dictionary" (OED) included many taboo words, albeit often with circumscribed definition and quotations, and "twat" was duly included in the relevant OED fascicle, published in 1916. The entry labelled it "low" and obsolete and noted Browning's "erroneous" use. There was no direct definition, but rather "See quot. 1727", a reference to the latest of the entry's five historical citations, namely the definition in the 1727 "Universal Etymological English Dictionary", which was in New Latin: ("female private part"). Two of the other OED citations included quotes: "Vanity of Vanities" and a c.1704 bawdy verse with a variant spelling: "At last, as groping thro' a dang'rous Street, / Where Stones and Twaits in frosty Winters meet".
The two unquoted citations were a 1656 translation of Martial's "Epigrams" and a 1719 bawdy song by Thomas d'Urfey. In 1986 the "Supplement to the OED" deleted the "obsolete" label and added twentieth-century quotations and the figurative insult as a second sense.
Besides Thomas Wright's 1857 dialect dictionary (" ") the word also appears in Joseph Wright's 1892 "Grammar of the Dialect of Windhill" ("twot ") but not in the latter's 1905 "English Dialect Dictionary". The 1950s Survey of English Dialects recorded the word at several sites as the term for a cow's vulva.
Edward Bulwer-Lytton's 1870 science fiction novel "The Coming Race", uses it to mean tadpole in an apparent satire on Darwin:
Modern use.
In August 2008 Random House, the publisher of the children's book, "My Sister Jodie" by Jacqueline Wilson, decided, after receiving three complaints, in future editions of the novel to reprint the word "twat" as "twit" so as not to offend readers or their parents.
In a 2009 breakfast radio interview, UK Conservative Party leader David Cameron quipped, "The trouble with Twitter, the instantness of it — too many twits might make a twat". According to presenter Christian O'Connell, Cameron did not realise the word could cause offense until Gabrielle Bertin advised him afterwards to issue an apology.
UK punk poet John Cooper Clarke included the poem "Twat" on his 1979 album "Walking Back to Happiness". It has been described, by Nick Duerden of "The Independent", as "memorable".
In his 2011 book "Filthy English", linguist Peter Silverton asks: "Can you distinguish an utter twat from a complete prick? I think you can. An utter twat knows not what he or she does. A complete prick does."

For the purposes of film certification, usage of the word is not considered as serious as many other swear words. It is listed by the British Board of Film Classification as an example of "moderate language" for the 12 certificate. However, the film "Kes" originally released in 1969 and given a 'U' certificate by the then British Board of Film Censors, denoting suitable for children, has in later years been re-certified PG in the United Kingdom, meaning: "All ages admitted, but certain scenes may be unsuitable for young children. Should not disturb children aged 8 years or over", despite more than one instance of the word. The word also appears in writing in an episode of "Fawlty Towers" (the letters on the sign have been rearranged to say "Flowery Twats"). The episode has a 12 certificate.
It also is not on the list of the seven dirty words made famous by George Carlin in his 1972 monologue "Seven Words You Can Never Say on Television", perhaps because the word is much less common in North America than in Britain, although it was used as a term of insult in Mel Brooks' comedy western "Blazing Saddles" (1974).
