They might not be able to answer your question untill Monday because right now they are pretty busy having a debate about if breadcrumb is one or two words. Cheers!
When I worked in an office, the correct form would’ve been an FFS because everything had to have a three-letter abbreviation or you’d get an IGN and have to take an SLM and then fill out a TSF.

It's "for f*ck's sake", as in "for the sake of f*ck". This phrase doesn't have any literal meaning, but the word "sake" is usually used with "for". "For the sake of goodness", "for goodness' sake", not, as some people say, "for goodness sakes".
