Term that is military in origin, and used to refer to officers in associated positions of power and resulting decisions that resulted in: poor decision making, emotional reactivity, increased number of casualties, and an overall sense of distrust in poorly-qualified leadership.

Currently used in popular culture to describe any situation in which: extrememly poor decisions are made for the purpose of very tired and predictable personal gain, without consideration for how decisons impact others, and an overall sense of intimidation due to lack of competence and personal responsibility by the aggresor.
Rob: "May I have permission to take a piss? Oh, and by the way, everyone is questioning your authority."

Lizzie: "No, you need to hold it for another 43 minutes and I don't care who does what. I've already thrown everyone under the bus, let's sit back and watch it unfold. I created this cluster fuck."

1) a bad situation that involves many different smaller situations to create one massive insanely intense ordeal.

2)when to many things happen at once, making it extremely hard to comprehend.
1) Holy shit! i can't believe my girlfriend was fucking your boyfriend, and they both got into a car accident, and your brother just got arrested, and Jimmy is trying to commit suicide! This whole day was just one big clusterfuck!

2) Wait...i dont understand this movie, who the hell is that guy and why is he now pointing a gun at that other dude..? And when the fuck did they go to the jungle?

a extremely confusing situation (from a comparison to a chaotic session of group sex)
