shit crust

After you take a deuce and don't wipe you ass properly you have a tendency to create shit crust. This is most noticed when excersizing, you have a burning sensation in the poo hole region. Also caused by having wet farts due to spicy foods.

Dude, I can't keep up this shit crust has lit my ass hole on fire.
