Reverse Diarrhea

When you go take a dumb/crap/shit and your shit hits the water hard enough so the water ends up going up and the water touches your ass.

Bob: Well my day is ruined!
Jack: Why?
Bob: I had reverse diarrhea
Jack: wtf is that?
Bob: Its when you go shit and your shit lands in the water really hard and the water splashes against your ass.

Reverse Diarrhea

Taking a shit and then painfully shoving it back up your ass.

I went back to my ex and now I have a bout of reverse diarrhea. Lesson learned!
