You leave some alphabet soup on the stove to heat up as you bend your partner over the armrest of a couch, you then pry their butthole open very wide and use something to keep it open. Once the soup is piping hot you take it and pour it inside of their dark abyss, causing an excruciatingly painful burning sensation that will leave them(me) squirming, writhing and groaning in pain or maybe even pleasure if they're anything like me. ;) Then you put ice cubes in the burning hot soup to cool it down faster, which in turn causes a painful contrast between the heat and the cold. After it cools some down you indulge on the delicious but slightly poopy vegetables and alphabet noodles, you slowly scrape up the side with the spoon making their sphincter quiver. Once you've got all the goods out you butt chug the rest of the poopy juice and they quickly run to the bathroom before the remainder of the poopy soup spills out of them all over the floor.
Chill bro: I can't wait to butt chug some sphincter soup out of your fart box later.
Non-Chill sista: Can't we just do something normal for once? I think I'm infertile after you did that upside down salsa thing on me.

bowel movement.
bowel movement.
Margot smiled and then produced a little audible chortle as she had a sphincter memory of her early morning blowout where she gave birth to a very large fudge python.
