The word is used to describe graffiti vandal payback. To cain a grafitti artists artwork is to write 'is wack' over the top of their name or to the side with an arrow pointing to their name.

A horrible biology teacher who spends most of the class period talked about sex and drugs instead of teaching then expects everyone to do well. Claims to be "open-minded" but has insulted religions and inferred that anyone who preforms rap deserves to die from AIDs. Also an arrogant asshole.
Man, that Cain is such an asshole. He made me stand for the entire period just because I nodded off a bit once.
