look up any word, like donkey punch:

Since the prices of gas are not coming down and there is no relief in sight, "relief at the pump" NOW means taking a piss on the pump, dump on the pump, or displaying some other form of aggressive or disagreeable behavior.

Urinating or defecating on the gas pump.
Jack was so ticked off that gas was $5.00/gallon when he was on his ski vacation that he got "relief at the pump" by peeing on the pump! What an idiot! Still, I can't say I blame him!
