Pronounced like History, except with an "Sh" added.
Basically, a Shitstory is a person's individual past or present past, that has been anything but decent.
A person that has a Shitstory, had an extremely rough and tumble childhood. They were either abused, molested, raped, had serious familial problems or the likes. Even those that had a difficult time growing up, due to the typicality of youth, can even have a Shitstory.
Shitstory doesn't just denote childhood. It also encompasses adulthood as well.
