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.

AKA SFS The shit fart separator is the divice inside your ass that separates your shit from your farts. Without this divice everything turns into a shart.

Post Shit Fart(s) or PSF syndrome
after taking an exceptionally large shit, the series of farts that come afterwords to really clear the bowels out.
