when you're doing anal and you cum in her ass at the same time that she has explosive diarrhea. You also took too much viagra and at this moment your dick explodes, leading you covered in cum, shit, and blood.

Guy 1: hey man, im thinking we go to the movies this weekend! Just you, me, and Shawn.
Guy 2: Dude, didn't you hear? Shawn can't go; he's in the ER after his one night stand resulted in a hot fudge sundae with a cherry on top.
