When 2 or more people release a rancid fart in a close proximity to each other.

When you eat dirt for the first time and leave your family to build a shack in the woods

When an individual sits down on the toilet and anticipates a "no wipe" condition. In doing so they flush the toilet as the bowl exits the colon and in a brief maneuver they stand up and exit the room, often in the amount of time it takes just to just take a leak.

When one takes a horrendous shit and after wiping their ass the toilet paper is blank.

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.
