A sexual indulgence not at all involving the Iranian people or its beliefs. The act entails dousing oneself in plutonium and masturbatory fluids while religiously praising the glory of our Dear Leader, Kim Jong-un. Afterwards, the individual must sneak through the Chinese border--Seppuku must take place if the individual in question is already within the nation of China--and continue to obtain nuclear launch codes on which he/she will smuggle into Iran via the anus so that a large group of security guards will have to manually retrieve the said object with their hands. This is done solely for the pleasure of the individual.
Guy 1: Shit, brah. I got so zobbled last night that I participated in an Iranian Cluster Fuck with that mentally crippled cousin I told you about.
Guy 2: The Holocaust was a lie, bro.

I group of people, cars, or animals that seem to all be at the same place at the same time, preventing each other from moving on. A seemingly unmoveable mass of objects that looks totally inefficient.
Dude, the traffic tonight was a disaster!! There were so many cars in this one accident, it looked like a Mongolian Cluster Fuck.

The recruits were given the command "To the Rear, March." Half of them kept going, a few went to the rear, and the rest just stood there with beer and sausage. It was a Bavarian Cluster Fuck

Slow moving traffic on the highway caused by several people driving slowly holding back traffic and preventing anyone from passing them.
On the way to work I ran into horrible traffic. We were moving at about 45 MPH on RT3 and when I reached the top of steep hill I could see three asshole preventing anyone from passing them, causing a rolling cluster fuck.
