A sexual act where a girl is sleeping with her mouth open, then the guy poops in her mouth and duct tapes it closed quickly. This usually results in quite the funny face when she awakes.
Guy 1: "My great aunt fell asleep in her rocking chair so I gave her a big dookie dreamer. You should have seen the shit fly out of her nose when she woke up."
