To ridicule an opponent by doing significantly more than what’s necessary to beat them. The origin of the phrase comes from Goldeneye 007 for N64 (or any shooting game) in which someone disgracing the body will continue to pepper their opponent with bullets even after the initial kill. Disgracing the body has no effect on the outcome of a game — it’s more just to humiliate the opposition involved.
Michigan football is leading Rutgers 78-0 with five minutes still to play; Coach Harbaugh apparently really wants to disgrace the body.
An insult said by a character from "Purrfect Apawcalypse: Patches' Infurno" by Patches himself. He uses this term by complaining how he has to live in another character named Angel's body, also calling Angel a twink.
(Fun Fact: Patches and Angel were dating at some point, so it's kinda understandable why he considers him a twink.)
