Verb- The contraction of the ass sphincter to prevent an enormous shit from ejecting from the anus. The contraction usually takes place when the turd is slightly popped out. This contraction causes the turd to return inside the anus. Analogous to the motions of a prarie dog (hence the name) that sticks its head out of the ground and goes back into it.

The act of a turd poking its top out of ones anus repeatedly

In a large, open plan, cubical filled office, this is where one inmate (or employee) stands up in his/her cubicle and looks arround. This is often followed by other office workers standing up and looking around to see what all the fuss is about, in a style reminiscent of those loveable creatures, prarie dogs.
