stinky jackpot

This is when a man is recieving oral sex while standing upright with one leg raised and his foot resting on a chair or the edge of a bed. Meanwhile, the person giving the oral sex is reaching between the other persons legs and catching his feces in their hand. The idea is that this resembles a person operating the lever of a slot machine and winning the jackpot, or in this case, a "stinky jackpot".
