A Chupacabra Butt Party, also known as a Chocolate Eclair, is a sexual act in which a man has intercourse with a woman's anus, he takes a particle of feces known as a Dingleberry and plugs his penis hole with it. The final step is when the man asks the girl to "finish him off" with a blow job, at which point he ejaculates, blowing the Dingleberry into the girl's mouth, giving her a taste of doodie cake.
