The Perfect Storm is created whenever many activities that individually would cause one to shit are combined into one ridiculous brew. A Perfect Storm could be created after a heavy night of drinking when someone decides they want to eat taco bell, smoke lots of cigarettes, drink a venti coffee, and then go on a long walk. The Perfect Storm is normally an emergency situation.
