This requires 3 people. The first person is laying on the floor of a porta potty with porta potty juices in their mouth. The second person poops in the first person's mouth while receiving a blowjob from the third person. The poop splashes on the first persons face. The third person also pukes on the second person's penis. Either the second or third person smears the poop on the first person's face like football facepaint.
