street sweeper
A person who, acting alone and without gang affiliation, forcibly ejects crips, bloods, pachuco boys, and other predatory criminals and terrorists from public places. He removes one or more greasy slimes at a time, either temporarily or permenantly. He works freelance, and is not a fuzz, a cop, or other deputized hireling.
Bumkicker Slade was, in his younger days, an infamous Oakland street sweeper. The local homies warned each other about him, saying "Ooooo weeee, watch out fo dat white boy. He be crazy!" A cool shotgun was named after him because it was almost as effective.
