Crowd Killer 

An ego maniacal man child with no social awareness or self control. Their natural habitat is the hardcore show, where they are known to exclusively assault and batter people half their size, because it makes them feel "tough."

Did you see that 200 pound crowd killer punch that minor in the face? Wtf is his problem he's like 34.
