Schrödinger's Shat
When you're not sure if you shat yourself, or you only farted. You really can't tell, and the only way to be sure is to look.

Schrödinger's Shat
When you attempt a fart, but afterwards you think you may have let out a bit of shit in your pants instead. You're not sure though. Until you check, you can't be sure.
Oh no, I think I've got Schrödinger's Shat in my pants.
