The Reverse Stomach Pump is a sexual act that two people take part in. One person shoves a hose up the other persons ass, then the hose is turned on. Once their rectum or whole intestine track is filled, the person who now has water inside them voids it from their body. Either onto the other
participant or their clothing from them to put on later.
"I'd give an arm and a leg to see Martha Stewart and The 1960s Robbin from Batman do
the Reverse Stomach Pump!"
"Brian that's not how you are
supposed to start conversations with your dying grandmother..."
