The word may have been used as a term of endearment in the Middle Ages in England, but I doubt she is that old. My ancient dictionary has it used to describe "a woman used as a sexual object." That fits its use by football players.
In Chaucer the Wife of Bath spelled it "queynt" - "you shall have queynt enough before the night is through" and Shakespeare in Henry V has Katherine punning that English ladies call their dresses "cons" (a mispronunciation of "gowns"). So a medieval scholar might not be offended, but the rest of us damn sure are!
