Top Definition
The act of inconsiderately and deliberately causing diesel soot to come out of a trucks tail pipe or smoke stack on public streets or other inappropriate places. People who oral cole have no consideration for anyone in diesel motorsports or the general public. These people are posers and do not contribute to diesel motorsports in any meaningful way. Their actions are also the driving force in the public outcry to ban large diesel events.
That douchebag just got ticketed for oraling cole.
