The area designated for urination upon immediate adverse survivalsituations for sanitary purposes and disease prevention. Typically a corner.
Courtesy of The Office, when trapped on an elevator:
Pam: Dwight! What are you doing? We've only been in here for like two seconds!
Dwight: I've got 56 ounces of fluid in my bladder and we have to establish a pee corner!
When a toilet is found previously containing urine and you do nothing more than to chip in. Mostly found in Men's rooms and mostly a product of the rule "if it's yellow, let it mellow."
"The dude before me didn't flush so I just chipped into the PeePool"
That really frustrating moment in our lives when you really need to go pee but you don't want to because you are lying comfortably in your bed. Usually occurs when you wake up in the middle of the night from your sleep.
Mike woke up at 3 a.m. and realized he was in some serious peelimbo after a heavy night of drinking. He ended up wetting the bed because he felt too comfortable to go to the bathroom even though it was a few steps away.
