Anal sex with a female who has diarrhea. The sloppy kind. You take an egg forming stencil for the McDonalds egg mcmuffin and let it drip from the tip of the old yogurt cannon. Once it solidifies, you punch the girl in the face "hockey style", and slip the sludge puck back up the processed food removal orafice.
Man, that chick tried to stop the old sneaky sludge puck maneuver last night.
