When a man has explosive diarrhea into a turkey vultures beak/mouth. The turkey vulture is then electrocuted and skull-fucked by a wooly mammoth. afterwards, the wooly mammoth is usually enraged to a point of impossible rage and proceeds to stampede the man and bust a galloon of sperm in his face. This is know as the Sumerian Piledriver
i was watching a wild zoo porno when out of nowhere a wooly mammoth performed a perfect sumerian piledriver.
