bathroom tourist

A person who works on one floor in an office building, but uses the bathroom facilities on another floor. Possibly for better facilities, or possibly to avoid close co-workers while subjecting unfamiliar employees to the stench of their biological functions.

Even though he works on the 4th floor and there are facilities there, Jerujohn is a 14th floor bathroom tourist, making 14th floor employees wonder who this guy is, and why he's using their toilets when there are perfectly good ones on the 4th floor.

A phrase used to indicate, "Not a chance."
