look up any word, like eiffel tower:
 
1.
The point at which a bathroom becomes one in & one out. Can be as a result of only one available toilet but ultimately occurs when the demand for humans to release their toxins becomes greater than the supply of facilities, which causes a line to form outside the bathroom.
Dude 1: Dude, I've gotta piss like a race horse.

Dude 2: Me too bro. Let's go find a tree, this bathroom has been steady state for days.

Pedestrian Canadian: steady state bathroom, eh?
