A jerk poop is where a person needs to poop really bad but waits too long to do it and when the time comes to poop..its a jerk and won't come out.
I better take this dump right meow or in an hour or so I'm gonna have the worst jerk poop.

A poop taken while jerking off. Can also be used as an insult, best used in the heat of the moment to bring someone down a peg or two.
UGH! I HATE YOU! You're such a jerkpoop!
