A term referring to marathon gay sex in which intercourse is so intense that balls slap back and forth between the partners like ping-pong balls and paddles.
"You shouldn't go over there right now, the newlyweds are back at it again with the marathon sex."
"A ping-pong championship? Again? They're ridiculous."
