When someone from or around Superior, Wisconsin tries to hit every bar on Tower Avenue in one night. There are 36 bars on Tower Avenue, and doing the Power Tower means you start at the first bar (at the beginning of Tower Avenue) and hit EVERY bar consecutively on the way down. It is a very difficult task.

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life
