"An English historian has come across the word ‘fuck’ in a court case dating to the year 1310, making it the earliest known reference to the swear word." Source: Medievalists.net (2015).
"Dr Paul Booth of Keele University spotted the name in ‘Roger Fuckebythenavele’ in the Chester county court plea rolls beginning on December 8, 1310. The man was being named three times part of a process to be outlawed, with the final mention coming on September 28, 1311.
"Dr Booth believes that 'this surname is presumably a nickname. I suggest it could either mean an actual attempt at copulation by an inexperienced youth, later reported by a rejected girlfriend, or an equivalent of the word ‘dimwit’ i.e. a man who might think that that was the correct way to go about it.'"
Note: The origin of the F-bomb is still kind of murky. There are several bogus etymologies floating around out there; for example, one popular explanation is that the word started off an acronym meaning "For Unlawful Carnal Knowledge," but that's effing nonsense. According to the Oxford English Dictionary, "the word is 'probably cognate' with a number of Germanic words with meanings involving striking, rubbing and having sex or is derivative of the Old French word that meant 'to have sex'."

Wherever it came from, the F-Word is one of the most essential words in the English language. American society, in particular, couldn't function without it and we can't avoid blurting it out even on live TV.
