Coal Rollin’ is an American backwoods trend, where people who love their trucks modify the engines to spew out black smoke. They then video the fumes and post the results online to antagonise environmentalists.

Some view this as the archetypal gun-toting, god-fearing US Republican mind-set in action – and assume that it’s done purely to give the finger to the sort of tree-hugging, dope-smoking commies who drive electric cars.

However, when KG tracked down some coal rollers and what he found essentially is that they mostly do it because they think it makes their trucks look dead cool, rolling along, blowing out black smoke. They don’t hate the environment – they just love their trucks!
