BFM
Standing for "Big Fucking Mess," this acronym can be used to describe a situation that is out of control or generally in a state of disarray.

It is especially useful in situations when it is unacceptable to utilize the word "fuck," such as at a workplace in front of your superiors or in front of your children.
We've lost 25% of our funding for the year... What a BFM!
