Etymology: Middle English "buffard" meant "idiot," and this term appears to descend from it. The link rests on the similarity of the forms and the match in sense, so it is best treated as a probable rather than a documented origin. The "buffard" form suggests a term of insult for a dull or foolish person, which is the sense the earlier spelling carried.
