When Gwen Shotwell was asked about the acronym BFR on international television, she replied "Big Falcon Rocket". Lovely response, quite dependent on context!
This is like how I use 'ofc' to abbreviate 'of course'. Once upon a time the 'f' may have stood for something, but I never use it that way. For me, 'the F is silent'.
In polite company you say "The article" or "read the manual" and patiently await your reward, which is their asking "what does the 'F' stand for?", to which you reply only with a condescending look and raised eyebrow(s).
That look of realisation is precious.
I've manufactured this experience once or twice, and it's wonderful.
Digestible maybe, but swapping "friendly" in for "fucking" changes the tone and intent of someone's statement. At least "freaking" expresses similar, if muted, exclamation.
A recipient who is being not-so-subtly reproached with an F-bomb acronym might misunderstand what is being implied.
