Heh. “Guy” has some interesting history. It originally referred to Guy Fawkes, because that was his name. Then it came to mean any person, gender neutral, then it became any man, now gendered, but the neutral definition never went away, so we have both meanings floating around still, but the original meaning, an effigy of Guy Fawkes, died.

(I skipped a few steps in there because they’re not relevant between guy Fawkes and any person)
