Used when “shenanigans” is just not adequate. A shitshow denotes general craziness, debauchery, drug and/or alcohol use, drama and sheer insanity all occurring simultaneously. One does not usually realize the shitshow is occurring until the following day.
Ex: Leah: Oh my god. Can you believe what happened last night?
Skyy: Girl, that was fucked up. What a Shit Show!
