At the Coventry convention, Gerry Anderson said this explaining the callsign
"F.A.B." in Thunderbirds, so I suppose that it can be taken as canon:-

> It is derived from the 1960's common praise expression "fab!", which is
> short for "fabulous!". It was not intended to be the initials of any
> particular phrase. But many people down the ages have suggested words for
> this "F.A.B." to stand for, some of them very rude.
