bashful bladder
Bashful bladder is stage fright is shy bladder is pee shy is pee anxiety and is paruresis which is a social phobia which means whenever you are away from your home toilet you can't piss no matter how bad you have to go and develop a strange, noticeable, tender bulge in the area below your belly button.
When you have bashful bladder your 9 hour day at high school, at work, at a rock concert, or at a football game is pure, excruciating hell, the revenge of too much chlorinated water or too many cans of Bud and sphincters that won't budge.
