Whilst working on the Jackson Pollock Memorial Software Extravaganza ("Throw some crap around and see what sticks!") my co-workers and I are naturally inclined to make snarky comments. Today co-worker Steve S. and I were leaving one meeting and I said something to the effect of "Cluster, meet fuck. Fuck, cluster."
Steve mentioned that this wasn't a clusterfuck, it was a whole collection of clusterfucks. Which, naturally, lead us to wonder what the collective noun for clusterfuck is. Eventually, after pulling up some Wikipedia pages ("Lists of Collective Nouns A-M") and throwing out some suggestions, Steve came up with "a Murphy of clusterfucks".
Which just about sums it up.
