Vomiting while pooping or pooping while vomiting.
While sipping back on a little too much of daddy's old scotch, you begin to feel nauseous as your previous meal catches up with you. Then, the real party begins. A mass explosion, with vomit exploding out the front and your feces exiting the rear. Thus, you have begun the ol' dirty double discharge.
