In this case, it's that I need a good substitute for the word "clusterfuck." I can't just use that word in class, but it does often seem to be the mot juste, and I need a synonym.
I'm glad to see it's come up on Ask Metafilter... not that there is a good answer. Debacle? Trainwreck? Imbroglio?
I think clusterfuck is unique.
