shit-fart separator 

The shit-fart separator (AKA shitfart separator) is the muscle inside your colon, just above your bunghole, that is responsible for separating shits from farts. Usually a dormant muscle, the shit-fart separator is often only noticed if it's repeatedly squeezing and churning when one has diarrhea. The work of a healthy shit-fart separator usually results in dry farts.

I had bad diarrhea, and my shit-fart separator was in overdrive.

My shit-fart separator failed me and I accidentally sharted a little in my underwear.
