F**K is a government created abbreviation derrived from the 1860's-1880's Comstock prosecutions, particularly the prosecution of author D.H.Lawrence and various book sellers for distributing the book "Lady Chtterley's Lover". The extensive legal history showed Court pleadings that repeatedly abbreviated the phrase
             " Federally Unlawful Carnal Knowledge"
with the first four capital letters of the phrase. IT WAS CREATED AS A LEGAL ABBREVIATION...HOW ELSE WOULD THE OBSCENE WORD "F**K" BE SPLASHED ALL OVER THE COMSTOCK TRANSCRIPTS AND BOXES OF RECORDS??? (Hint-it wasn't obscene yet!!!)

As for the pseudo-intellectuals who want to reconstruct it with ancient Germanic, French, Scottish, and Latin phrases meaning "to move quickly", etc., that's why they're **AMATEUR** linguistic analysts....

This is a government-created good old-fashioned ABBREVIATION that came to mean, by usage, the Federally Unlawful Carnal Knowlege that it was once used to depict in the texts of the legal arguments. We abbreviate it on the internet because if we don't, the stooopid amateur linguists get filtered out, and then they can't make themselves feel important by being brilliantly stooooopid historical revisionalists...

By the way--abbreviate all you want--I won't be back. You f***'in' people are stoooopid---get a life!!!
