Someone with an absurdly loud voice. A closet raa. Consistent liar and excellent impersonator of various bo selecta characters. Usually fat and short, and with few friends and little charisma. Stunning resemblance to members of alvin and the chipmunk gang. Basically the ultimate wanker.
Man in Bar: That fat guy is well loud, wish he'd shut the fuck up about shagging prossies in prague.
Man(2): Tell me about it, complete tosser
Man(3): Yeh I know, hes a right greg peach.
