Moroccan Landslide
When a lover drinks an entire bottle of laxative in order to perform this act, then later that day has the other cup the asshole with their mouth, and directly shit down their throat
Patricia: "I'm at the store, do you need anything?
Brian: "Grab some laxative."
Patricia: "Why?"
Brian: "You know that you need to give me a Moroccan Landslide later."
