Casebeering 

drinking a whole case of cheap beer to ones self at sporting events, then acting belligerent, yelling screaming,fighting, cursing loudly around small children, throwing childish tantrums, starting fights with younger smaller people, and being a douche in general

at the go-kart races bob was totally casebeering this kid 1/2 his size into the wall, then punched her mom in the face on the way out.
