In an email to my new employer's HR department about a payroll problem, I started to type "there seems to be a snafu in my pay". However, I then reflected on what (I understand) "snafu" originally stood for (situation normal, all f****d up). However, the term seems to have worked its way into somewhat broad acceptance. So, has "snafu" either become an acceptable term independent of its original meaning, or do most people not know what it is short for, or should I just avoid it?
Edit about the use of the term: There have been a few statements about how this particular use of snafu doesn't fit the term; i.e. that this is a single occurrence, but that using the term implies the problem to be the normal state. While I see how that contradiction may seem to exist, it's my observation (and that of others, including other statements in response to this question) that the term is usually used in response to a particular incident. While there is (obviously) room for misunderstanding I think the "situation normal" part of the term comes more from a view point that life/the universe/everything is messed up, and this single event is just one example of it.
