In terms of California Latin gangs, Sureno or Southern California Latin gang member will call the Norteno or Northern California Latin gang member a buster. This is because Buster means someone that is unwilling to comply with your will. The Norteno have for years shown great resistence toward the Mexican Mafia or the EME. They don't pay their taxes, they show no respect and they feel that they are independent. This is why there is so much animosity between the Surenos and the Nortenos.
"Ay homie, he said he's from Fresno, go check that fool to see if he's a buster..."

A poor, innocent crash-test dummy. He has done not a thing to deserve the torment regularly inflicted upon him by Adam and Jamie, those cruel bastards, on the TV show Mythbusters.
Buster is a true American hero.
