buster
 n.— «When the Sureños saw Adorno and his red shirt, they decided to take care of the “buster” in the alley, a derogatory term Sureños use for Norteños. One man drove slowly down the alley. Another ran up to Adorno, said “it’s all about Sur Trece,” referring to the Sureños, then shot him in the head, execution style.» —“In The Line Of Fire: Gang members killing innocent people” by Susan Herendeen Modesto Bee (California) Sept. 19, 2007.
