Clench Robot

The awful, terrible walk that you during the final steps before a major and unexpected gastrointestinal event. The walk is slow and robot-like, as you must keep your sphincter tightly clenched to avoid disaster. Usually takes place once you've reached your home, or if you are in public the bathroom itself.

"I was speed-walking through the grocery store, and once I found the bathroom my body could sense the imminent relief. I nearly lost it right at the door to the bathroom and had to do the clench robot all the way to the stall."
