hooker
n.— «Hook: An invaluable offensive tool in the fight game, but only a precious few are able to use it to devastating effect. Those who can and do, are often referred to as “hookers”, and not in the pejorative sense. De La Hoya is a hooker who can get you out of there with one well placed left hand.» —“Oscar De La Hoya Vs Floyd Mayweather JR: Don’t Bet Against The Golden Boy” by Russ Greenspan Ringside Report Apr. 22, 2007.
