When you have to go poop so bad that it keeps coming partially out and you suck it back in to avoid messing your pants. This usually happens on a long trip, or when you can't get to a bathroom, or when it would be socially inappropriate to take a dump.
"I had to take a crap so bad I was prairiedogging like like a whackamole!" Or....."Me and Cheryl were out on a date and I had to take a crap so bad I was prairiedogging!"

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.

When one's feces repeatedly breaks the anus plane, touching air, and returning from whence it came. This is generally due to inconsiderate parents insisting, "We'll be leaving in five minutes" throughout the course of a two-hour trip to Lowes.
I was prairie dogging when i was watching 2girls1cup, but i was on the edge of my seat, so i stayed put.

When your feces starts bobbing itself in and out of your anus because you have to take a big shit but can't find a bathroom and can barely hold it in. Similar to a prairie dog popping in and out of the ground
Dude, I gotta take a shit so bad I'm prairie dogging it
