European Double-Decker

Performing a European Double-Decker involves a male and female deficating in the bowl and resevoir (respectively) with the male straddling the resevoir, thus giving him access to perform cunnilingus on the female.

Brad and Angela just got back from a European Double-Decker in the bathroom. You can tell by his white mustache and brown soul patch.

Double decker

When a guy is peeing in a urinal while another is peeing in between his legs. (In a heterosexual manner)

Hey bro, we both have to pee and there’s only one urinal. Let’s hit a double decker
