Aftershit

An uncommon phenomenon that occurs after taking a normal shit, then hanging out on the can do to relief or for the sheer stench of it. After no less than a minute (or more) later, unexpectedly taking another shit (usually lesser than the first).

This phenomenon is similar in theory to what a woman experiences as the afterbirth.

An Aftershit must be separate from the original shit by at least 60 seconds to be considered a true Aftershit.
Delayed shitting do to constipation and continual shitting do to diarrhea are not considered true "Aftershits"
