In similar vain, whilst probably apocryphal, Royal Caribbean claimed to have used the codenamed moniker SFB for their most recent ships – “seriously fooking big”.
Not particularly apposite, but I did some media training some years ago too, part of which was around not using acronyms/jargon in public unless you’re absolutely clear on the meaning/origin. The example given was that a police force used to refer to petty crimes carried out by lowlife scum as “SNAF” crime, derived from SNAFU – in this context “sub-normal and **** useless”, it became part of the lexicon, without real consideration for what it actually meant. Eventually someone used it in an interview, and was then questioned on what it meant. Not ideal.
Also not necessarily apposite, but amusing, there are plenty of good medical ones here.
