A phrase that describes what teh leetest (not really) executives must do after their three hour power lunch. It also might describe a mathematical term, such as n to the power of pee, but that's a bit more nonsensical.

It is also when you have a limited time to "relieve yourself," and you do so as quickly as possible. Usually leads to a return trip to the restroom half an hour later.
Bob just got out of his batter-powered power lunch, and really needs to take a power pee before the shit hits the fan.

Lisa was told by her teacher that she could visit the restroom, as long as she chopped down the mightiest tree in the forest with A HERRING, and took less than 5 minutes to complete that task, as well as going to the restroom and finding a nice shrubbery for the principal. Any longer, and she would be expelled. That warranted a major power pee.

A male's method of cleaning a toilet's dirty skid mark by targeting a strong stream of pee directly on a stubborn brown poop mark that could not flush out under the conditions of a normal toilet flush.
After meeting his girl friend's parents for the first time at their home, he excused himself to go to the rest room. After he relieved himself of a huge dump, he noticed a large brown skid mark on the toilet. He then proceeded to target the mark with a power pee wash in an effort to leave the toilet sparkly clean.
