All Out Bombing. A graffiti crew from Los Angeles that was formed in the late 80s and which later became a gang (Avenue Oxford Boys) in the early 90s. Known to be ultra-violent and to be comprised of a multi-ethnic makeup...which is rare for a street gang in Los Angeles, in which most gangs are divided along racial lines. AOB had a pretty even mix of Asians, Blacks, Hispanics and Whites.
Don't fuck with AOB, those motherfuckers don't play.
See that carload of Black, asian and hispanic dudes with the whiteboy sitting shotgun? Those fuckers are most likely from AOB, let's get the hell out of here before they jack us or someshit.
