When you get so drunk at a party that you pass out and people put chocolate cake in your pants to make you think that you shit yourself.
Based on true story.
John was drunk and a little obnoxious so he woke up with an Alabama mud butt.

An after-shit is an uncommon phenomenon which occurs after taking a normal shit. Usually, minutes after completing your first dump, you unexpectedly shit again. Whether or not you are on the can is inconsequential.
John thought he was done in the bathroom, but one change of pants later, he learned to respect the dreaded after-shit.
