Buster (2008)

The story of a guy that anyone in his right mind would run away from. Or should run away from, since Buster spends all his spare time provoking strangers into fights, then refusing to defend himself as they pummel him 'til they grow bored. He's also a grifter, sucking his brother dry, and a cancer, sabotaging his brother's relationship with his girlfriend. Think of him as the patron saint of passive aggression, the don of all losers, or maybe just a regular guy who lost his mind trying to avoid growing up.
