billy

billy or billy club (BIL-ee) - n., a short rounded wooden club; esp., a police officer's club or baton.


There's many other meanings for billy, but this is club week so I'm only running this sense. For all of them, however, the origin is obscure but speculated to each derived (separately) from the male given name Billy, diminutive of William, though exactly how/why is entirely unclear.


Thanks, WikiMedia!
