The line that contains fuck reads Non sunt in coeli, quia gxddbov xxkxzt pg ifmk.
Deciphering the phrase "gxddbou xxkxzt pg ifmk", here by replacing each letter by the previous letter in alphabetical order, as the English alphabet was then, yields the macaronic non sunt in coeli, quia fuccant vvivys of heli, which translated means, "They are not in heaven, because they fuck the women of Ely".
A different false etymology, first made popular on the radio show Car Talk, states that the phrase "fuck you" comes from the phrase "pluck yew" and relates the origins of fuck to the myth surrounding the V sign.
During the Black Death in the Middle Ages, towns were trying to control populations and their interactions."Either this refers to an inexperienced copulator, referring to someone trying to have sex with the navel, or it's a rather extravagant explanation for a dimwit, someone so stupid they think this that is the way to have sex," says Booth.An earlier name, that of John le Fucker recorded in 1278, has been the subject of debate, but is thought by many philologists to have had some separate and non-sexual origin.None of these acronyms was ever recorded before the 1960s, according to the authoritative lexicographical work The F-Word, and thus are backronyms.In any event, the word fuck has been in use far too long for some of these supposed origins to be possible.
