a term often used by pro wrestlers to describe usually 2 or more opponents from the "other camp", implies they are bumbling knuckleheads, who's fighting style is similar to that of the "marx brothers"
> excert from long winded wrestling dialog : "so you and your your gibrones can kiss my"... the wrestler continues similar insults and harresment untill someone takes the microphone of him, or some actual wrestling takes place.
