When you have to drop a load so bad, the head of the turd keeps poking out of your ass then slipping back in. Similar to how a prairie dog pops up and down in their hole, appearing and disappearing.
We have been driving for two hours. I am prairie dogging a deuce. If you don't stop it will explode out into my boxers.
