When you fill a water balloon with your own diarrhea and throw it at someone, drenching them in your own feces.
John wanted to get revenge on Pete because he had screwed his wife the night before, so he decided to throw a Diarrhea Balloon at him.
When your poop turns out to be half solid, half soupy, so it is like pooping out the beans that you get at a Mexican restaurant.
I had the worst Mexican bean butt this morning. Was it the food I ate last night?
