When two individuals participate in a Daffy Pineapple, they insert a bendy straw into their anus'. one end goes in each of them and they participate in a game of tag where they release gas back and forth creating a vortex of fumes inside the straw. then they remove it from their anus' and in turn, suck both ends of the straws at the same time.
