Pompeii Pickle
An agregiously shameful sex act involving a very drunk, whorish girlfriend, a tube of Mentos and a diet coke. The girlfriend is positioned face down on the bed (or may be already passed out this way) and several of the Mentos are manipulated into her ass, accompanied by a string of low, drunken moans. The man positions himself carefully and loudly declares "I am the God Vesuvius" as he pours diet coke into her anus and rams it home with his pecker. The resulting epic eruption brings about destruction of undeniable historical significance.
"What the hell is wrong with Matt? Ian told me that he gave that carnie girl the pompeii pickle the other night on his couch. The whole apartment smells like shit and cabbage."
