A peeing fiasco - in other words, a situation in which one is simply unable to urinate, despite several efforts, because of a number of possible reasons, including but not limited to:
1. A boisterous neighbour in the neighbouring cubicle talking about his weenis.
2. Your friends cheering you in the toilet, "Go pee! pee! pee!"
3. A really really tall guy in the next cubicle.
4. The professor who taught you adaptive wiener filters coming into the toilet just as you try to let yourself go.
5. Someone washing their hands in the toilet sink and flicking you with water, yelling "pee hands!"
I'm waiting for you to leave before I pee, or I'll end up with a pee-asco.
