I just watched the movie A Knight's Tale, and the character Wat repeatedly threatens to "fong" people (as in "I'll fong you," clearly meaning some kind of bodily violence.)
There are claims around the internet that "fong" is an "actual word from old English" (sic, presumably meaning Middle English) meaning "to kick".
However, I can find no entry for it in the OED, nor in the Middle English Dictionary.
Is there any basis for the claim that "fong" is a Middle English word meaning "to kick"?
