The awesome substance that pours out of the exhaust of most diesel trucks. Easiest to acheive when laying on the pedal before the turbo spools up. Best done with behind the wheel exhaust when an expensive car is behind you with the windows open. Best done with stacks when being followed by a group of bikers.
Dude, check out this group of asshole bikers behind me. I'm gonna black smoke the shit out of them.
