Premature crapulation (PC)

Occurs when a man or woman experiences the need to drop a deuce and feels their poo starting to exit their bunghole or even expels a tiny bit of poo soon after the call of nature begins but doesn't reach the toilet in time.

After I pounded those protein bars about 30 mins later I was rushing to the bathroom but experienced another bout of Premature crapulation (PC) before I could get there.
