When you absolutely shit your pantaloons in a vehicle while all of the windows are up, similar to a mega dutch oven Everyone smells it and the driver crashes the car, killing everyone because of the cancerous stench. The scent lingers in the area for three years until it eventually smells like a bloody period queef and vaporizes into the atmosphere.
Yesterday I turned the car into a Pennsylvania Gas Chamber because of the Taco Bell I had an hour before.
