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.
Man i have to shit so bad that i'm prarie dogging.

First coined by Scott Adams in a Dilbert comic strip.
