A Punch-Out is a slang term in professional boxing referring to a boxer who boasts and taunts his opponent but can not hold his own in the ring in actual boxing competition. Informally defined, it could be best described as being able to "talk the talk" but not back it up in the ring. It may also refer to a training exercise, in which the boxer throws repeating Jab and Straight punches or "One-two Combos" until told to stop. This may be repeated one to eight times depending on the trainer
The term is outstandingly used in a quote the film Rocky II by Burt Young playing the character Paulie, who instructs Rocky to "Blow this punch-out!" in response to Apollo Creed's taunting at a press conference.
