Getting a blumpkin(getting a blowjob while taking a shit) and dumptrucking(Pooping in someone's mouth while they give a rimjob). At least 3 people are required for this.
Guy 1:" So I hear stacey and kelly give a mean blumptruck"
Guy 2: "damn dude, I knew they were whores, but I honestly didn't think they would go that far."
