He should not feel this great about destroying some poor kid's bike. But Trevor does. He's quite chipper as he runs the thing over, then proceeds to back up over it again, because overkill. Then he glances toward Stiles. Points at him.

"This is what happens when you're inconsiderate. You are entirely in control of your own destiny. Your fate. Which, in this case, is a shitty bike meeting its end."

Pause.

"Think of it as a mercy killing! Fuck your fixie, you hipster." Yes Trevor just said that. Then he's shifting it back into drive, prepared to just squeal off into the streets again if Stiles has no rebuttal.
