Walking the brown mile

Used to describe the uncomfortable walk to the nearest toilet to drop ones load. Can also be seen in the workplace when a thoughtful colleague will often bypass the nearest shitter and make the walk to a more isolated location to make the experience more relaxing .

Hi Bob, good weekend?

Hi Sue , great thanks, I can’t stop and talk , I’m walking the brown mile right now but I’ll meet you for coffee at 10 ?
No worries Bob, have a safe journey.
