Derived from "shit storm, it is when everything bad that could ever go bad happens all at once, pretty much putting you as close to death as possible, with out actually dying. Usually will be a life changing event.
Max was in a total fucking shit storm today man.
Ya, he was in a car accident, lost his legs, is blind, got cheated on by his wife with his best friend since preschool, and got his balls cut of by accident when they were prying him from the car.
Wow, at least he's still alive.
