Some one who beats up people for no particular reason. Basically a bully.
person 1 "Hey, did you hear Jim-Bob beat Tyrone's ass and Tyrone was minding his own business!"
person 2 "Yeah Jim-Bob is such a red neck, I heard he kicked him with those roach stompers like the guy in Billy Jack!"
Person 1 "Maybe it was Tyrone's purple fuzzy pimp hat?"
Person 2 "Who knows Jim-Bob's always starting shit!"
