Occupy Movement
When you take a dump in your boss's fancy restroom and yell 'Occupied!' at a rich guy who tries to open the door. You stay in there so long, you might as well be camping.
I took a dump in the boss's bathroom and screamed 'Occupied!' at a guy who looked like he had money to burn.
I was in that stall for so long, the guy had to call a plumber.
I told the guy, 'You can't even do your business if I don't want to.'
