Origin of the F-Word - taken from about.com's urban legends library

The word fuck did not originate as an acronym. It crept, fully formed, into the English language from Dutch or Low German around the 15th century (it's impossible to say precisely when because so little documentary evidence exists, probably due to the fact that the word was so taboo throughout its early history that people were afraid to write it down). The American Heritage Dictionary says its first known occurrence in English literature was in the satirical poem "Flen, Flyss" (c.1500), where it was not only disguised as a Latin word but encrypted — gxddbov — which has been deciphered as fuccant, pseudo-Latin for "they fuck."

According to Sheidlower, the earliest claims in print of supposed acronymic origins for the F-word appeared during the 1960s. An underground newspaper called the East Village Other published this version in 1967:

It's not commonly known that the word "fuck" originated as a medical diagnostic notation on the documests of soldiers in the British Imperial Army. When a soldier reported sick and was found to have V.D., the abbreviation F.U.C.K. was stamped on his documents. It was short for "Found Under Carnal Knowledge."

Two more variants appeared in a letter published in Playboy magazine in 1970:

My friend claims that the word fuck originated in the 15th Century, when a married couple needed permission from the king to procreate. Hence, "Fornication Under Consent of the King". I maintain that it's an acronym of a law term used in the 1500s that referred to rape as "Forced Unnatural Carnal Knowledge."

Undoubtedly the most famous use of this etymological travesty was as the title of the 1991 Van Halen album, "For Unlawful Carnal Knowledge."

other variant include:

The word fuck comes from colonial times, when someone would be punished for 'prostitution' It was an acronym for the words "For Unlawful Carnal Knowledge". FUCK was written on the stocks that held these criminals because "For Unlawful Carnal Knowledge" was too long to go on the stocks.

i think yimun told me about the "Fornication Under Consent of the King" thing before.

also manage to get this. i've always wondered what it means and how it came about :-

Fuck Spider - taken from http://www.talkingcock.com/'s coxford singlish dictionary

"Of uncertain origin, this term often connotes extreme frustration. The general consensus is that it originates from the Army (the source of many creative Singlishphrases), where a "spider" was dirt in the barrel of one's rifle. If during inspection, you found a "spider" in your rifle, you'd have to strip it and clean it all over again. Hence, "fuck spider" would either be a common expletive amongst recruits, or an exhortation by an annoyed inspecting officer/NCO. Some, however, believe it dates back to an old practice amongst boys to catch spiders in the undergrowth, house them in small boxes and make them fight."

so, do you know how to fuck a spider? my dad's ex-employee told me once that there is a way to actually fuck a spider. see, if u're on top, u'd squash the poor spider. and if the spider's on top, well, there's no point because u'll be to big for the spider. but there is ONE way to fuck a spider right. person who can tell me how it's done, gets to do it!
