The act of accidentally dropping a filthy steaming deuce while your humping the hell out of some broad/bro. Most commonly occurring after a high fiber meal.
I was in my parents room doing it in there shower with Joey and as he was railing me out he accidentally pinched a loaf on my parents shower floor, I look down and theres a Kirby bomb splat down on the floor.
