When a Robbie cheats a Rae, and a Matthew finds out and throws a hissy fit that the Robbie lied to him about it. Then they start fighting and drag everybody they are friends with into the fight. causing stress and a shitload of drama.

or

When someone brings fighting friends together to talk about there feelings. Which does not solve anything.

Also, a delicious chocolate candy bar with caramel, nuget, rice crispy clusters, and loaded with peanuts.
1. Robbie, Matt, and Rae, why are you sending us into this clusterfuck?
2. That talk last night was a clusterfuck.
3. I just ate one orgasmic clusterfuck.

A word I like to use without knowing exactly what it means. Usually I like to say it and make it sound dirty, because it has the word "fuck" in it.
It was quite a clusterfuck when I clusterfucked your mom in her clusterfuck last night.

Defined as the act of violent sexual congress, in which marauding soldiers in the latter days of the Roman Empire would pillage Convents and stab Nuns several times,then each soldier would 'fuck' the wound. This gives the impression of a group of men 'clustered' around a person, hence the name.
none needed!!
