Nomadic Colon
Nomadic colons are people who travel to restrooms outside of their work area (past the closest restroom) to utilize a restroom commonly used by another work group or on another floor.

The nomadic colon travels there for unknown reasons, perhaps from a fear of embarrassment from co-workers, a desire to defile new and unexplored territory, or for comfort reasons.

The nomadic colon is predominately male in gender, but female nomads have been observed.
Oh, man!  Some nomadic colon stunk the rest room on our floor!

I spotted the elusive nomadic colon when he emerged from our restroom and immediately entered the stairway to return to his home territory.
