The name of a curious clown woman you might find snooping around Mcdonalds after the sun sets. She usually appears in her clown form and may quite possibly be drunk off her ass. Young men should stay far from her, for she has little manners and may invite them and their cocks into her massive clown puss. Basically, a Doo-Da is a clown whore.
