The untimely, and extremely irritating feeling of having to pee, as soon
as you know that you can't
Example of this would be; right when you find your spot in
hide and go seek, whenever you get stuck in line, when your in the car-miles away from a
rest stop, etc.
"As soon as i found my hiding spot, I totally pulled an
untimely bladder, shit!"
"This line better move faster, I gotta take a
raging piss!"
"When's the next rest-stop?" - "25 miles" - ".....shit
i gotta pee."
