dude id just chill on it, karma is a bitch. eventually that dude will get fucked for something, and probably jumped/robbed/killed. Just take the good with the bad and get high. I knew a dude that would always try to rip off my younger friends but then eventually this kids older brother broke his right leg and right arm with a baseball bat and that fool got out of the game and moved to a whole new part of town. Karma.
