The Pittsburgh Plum is a sexual act in which an individual places a plum inside their own rectum and then waits until the acid in their butt annihilates everything except the pit. Once this occurs, the individual starts masturbating until they simultaneously bust their nut and shit out the plum pit.
Eugene surprised everyone at his 98th Birthday Party when he whipped out two dozen plums and had his own Pittsburgh Plum competition on his kitchen floor. However, it was to every party-goers dismay that only Greg could finish the feat by the time the party had ended.
