A slang term used in MMA (Mixed Martial Arts) to denote getting KTFO'd (Knocked The Fuck Out). The term's origin comes from a match that occured at UFC 56 between Rich Franklin and Nathan Quarry. Quarry was knocked out cold in brutal fashion by a left hand from Rich Franklin making this one of the most brutal looking knockouts in UFC history. The term is used rather liberally (mostly on MMA internet forums) at this point--essentially it is interchangeable with KTFO. But it's original intention was to denote someone being outclassed or outmatched (Quarry was undeservingly thrust into a title shot with then middleweight champion Rich Franklin for several inconsequential reasons) and then getting brutally knocked out.
