"To get the twat I got a knot, no more runnin' from the cops/
now I'm rollin' with Foxx because the block's hot."
- Jamie Foxx, DJ Play A Love Song
Much like cunt, the word twat is mainly used as a slightly vulgar slang term for a woman's vagina. It is not recent slang, however. In Henry Miller's 1934 novel Tropic of Cancer, he writes, "A man with something between his legs that could...make her grab that bushy twat of hers with both hands and rub it joyfully."
So where did the term originate? While there is no specific background, the word can be traced back to old English, where the term twat was most commonly used in reference to hitting someone hard; for example, "I twatted him above the head."
Eventually, this term came to mean the female genitalia. One of the earliest documented works was a satirical English poem from the 1660s, which read: "They talk't of his having a Cardinalls Hat/ They'd send him as soon an Old Nun's Twat."
Today, twat can be heard in a number of songs, like the one quoted from Jamie Foxx's album Unpredictable, released in 2005. The term also made an appearance in The Blow Job Song by Blink182 (which is a play off an old George Carlin skit).
Besides referring to someone's vagina, twat can also be used to insult someone. One may call another a "twat" if he or she is acting like an idiot or jerk. In the 2001 Academy Award Nominated film, Billy Elliot, the main character, Billy, is called a twat by his grandmother.
Lastly, one funny tidbit: today, in the United States, twat has another variation; it is the abbreviation for The War Against Terrorism (written, T.W.A.T.).
