After a long, wet, hard defecation, half wipe your balloon knot
and allow to dry, so that the remains have attached themsleves to the pubic hair around the arse cheeks.
Later, rub your arse crack over your victims face, using their nose as a scraper, rubbing off the 'coffee beans' into and around their mouth. Points are awarded for acurately dropping a bean into the screaming mouth. (1 point for each bean is the generic scoring.)
