Previously, its earliest written use was thought to have been in the 1500s. Booth’s discovery, however, moves that date up over 200 years, “shift[ing] back the rough historical consensus on the when the word widely entered the vernacular as a vulgar, pejorative term,” The Washington Post reports.

The word appears three different times in the 1310 document, suggesting that “Fuckebythenavale” was a nickname and not simply a one-time joke. “I suggest it could either mean an actual attempt at copulation by an inexperienced youth, later reported by a rejected girlfriend,” Booth said of the term’s likely meaning, “or an equivalent of the word ‘dimwit,’ i.e. a man who might think that was the correct way to go about it.”
