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'.

I like to read it as The Featured Article

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.

Fine instead of Freaking is much nicer.

I think "Friendly" was/is popular explanation where devs tried to translate their subculture into something generally digestible.

Or the fine article.
