I hate it when I wake up in the morning and I start taking a shower during shower rush hour and I can't rinse the shampoo out of my hair.

To shower for an hour means to jerk off in the shower. Usually people say "Why where you in there so long?" and you make up some lame excuse.

When doing something that causes physical,mental,or spiritual filth that far exceeds the very bowels of Hell(EX:Stan Lee selling Marvel Comics to the Corporation of Disney)... you must embark...the 12 hour shower. The action of taking a shower that last 12 hours, no more, and no less. For the ceremony to actually start you have to be in the shower for at least 2 hours prior. For if you embark on this journey of self revelation and stop the shower before 12 hours,you will explode in a flaming bag of poo and turn into a crippled rabbit. If you are in the shower for more than 12 hours, you will die right there, and in the after life you will have to listen to Ke$ha non stop. Only the most keenest of minds, the strongest of willpower,and the strength of Hercules can take on this task of Gods. It takes more than a century of training in several disciplines to accoplish this goal. So, do you think you have the balls?
Woman 1: "I was just rapped by Mickey Mouse. Time for a 12 hour shower."

Man 1: "I just watched the end of 'The Green Mile'. Time for a 12 hour shower."

Transvestite Alien: "I just saw the end of 'Alien vs Predator' and have lost my faith in my religion of scientoglogy. Time for a 12 hour shower."

Also known as an HSOP, this is a male's shower that takes an hour. Any male spending an hour in the shower is quite obviously masturbating in there.
