what noncreative people (usually fraternity and sorority members) use to describe a reckless, drunk, and exciting night! people that use this word might also use words like "haggard" "legit" and "debauchery." It's also very common to use this as a facebook album title.
Omg last night at Sigma Gamma Epsilon was such a shit-show, I can't even remember anything, except that red cup I was holding in every picture!!!
A display of ridiculousness. This ridiculousness could be measured in alcohol consumption, or by other controlled substances that is causing a group of people to look like idiots. It is not a "show," yet a display of behavior that is unappealing to the innocent bystander who wishes to not take part in such ridiculousness.
Everyone in that bar is drunk and acting like idiots, it looks like a total shit show in there-let's bounce.
The point in a night of cheerful drunkenness, where one moves past the point of fuzzy warmth into "OH SHIT!" territory, and then all the fuckin dawgs get let out the pound. This feeling is usually followed by a hangover that will hit you harder than a punk-ass kid that doesn't know anything about bumper-car etiquette, or a .42 BAC.
Oh man, did you see Willie last night.. Total Shit Show. He must have experimented with at least 2 beers.
