Top definition
A sexual act where two people point there anuses towards each other, and one person poops in the other person's anushole. The receiving end then sucks in the poop using the reverse fart technique. Then the person who recieved then becomes the sender, and the sender becomes the reciever. This continues until one person's anus muscles become tired and cannot continue vacuuming.
