Regardless of engine technology progressing to the point of nearly eliminating black smoke and producing nearly double the power of modded mechanically-injected diesel engine in stock form, a 'Coal Rollin'' owner will respond with a not-so-clever response of 'I'd rather be Cummin than Strokin.' Referring to his belief that his Cummins engine is better than International's Powerstroke engine series found in Ford trucks.
Then said WT decides to post youtube videos of their truck blanketing neighborhoods with black diesel soot. When stupid-ass white trash people turn the injection pump up on rickety-ass broken down 12V Cummins-powered Dodges and subsequently install 5' smokestacks in the bed of said Dodge.
