Rollin’ coal is the term for the trucks that smoke like they are on fire. This is done by some modification on the engine and on the exhaust pipe too, and the owners of the trucks like this black smoke too much.

The rollin’ coal trucks owners think that the black smoke is so cool that everybody will be looking at their truck when they pass. They even make some jokes with the black smoke when they are passing next to some pedestrians.

They ask the guy if he smokes, and if he answers yes, then they hit the gas pedal, leaving the guy in black smoke where you can barely see if there is anyone for half minute at least. This black smoke is not so environmental too, this is diesel fumes that are not fully burned because there is too much fuel coming in the cylinders of the engine, and fumes are created that way.

But the rollin’ coal trucks are the most interesting ones, the most powerful ones and the fastest trucks out there. That’s why they are so liked by the public even if the prank is on them.
