To over-fuel a diesel motor to the point that thick black smoke comes rolling out of the exhaust. Usually associated with modified or "BOMBED" diesels it shows you can actually make some power.

When your in a diesel truck and have the injection pump turned way up and you mash the throttle to overfuel the motor, thus making a cloud of black smoke until your turbocharger spools up. Best done in a 12 valve Cummins Turbo Diesel powered Dodge Ram pickup, as they are by far the best sounding and most reliable pickups built, plus, the pump is tuned with a screwdriver and allen wrench on the P7100 equipped engines. Also best done with a high dollar car behind you, preferably driven by an attractive female, homosexual male, city slicker, or tree-hugger.
"Hahaha dude did you see me rollin' coal on that stupidass tree-hugger in the hybrid Honda?" "Yeah dude, he couldn't see 20 feet in front of him"

Coal maintenance (affectionally known as CM) is the art form of maintaining steady coal heat to a shisha.
Most people will say it is the most crucial part of a good shisha session and there really is no excuse for bad CM.
Constant delivery of fresh coals to the porcelain in correct positioning is paramount. This is generally applied throughout the heart of the Middle East of by 'Coal Ninjas' and is the true sign of a good shisha bar.
