Shitfart Separator 

The 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 shitfart separator is often only noticed if it's repeatedly squeezing and churning when one has diarrhea. The work of a healthy shitfart separator usually results in dry farts

My shitfart separator failed me and I accidentally sharted a little in my underwear.
