Mike, an acronym looks like a word and can be pronounced - like RADAR - at least on this side of the pond. But BFH are just initials, like the proverbial RCH - something that’s tiny; i.e. you’re just an RCH off. Now there’s gotta be a word for initials that can’t be pronounced - there’s a word for anything and everything in English - but I knoweth not what it is.
Get the sockit wrench was a phrase often used where I worked: if the nut on the end of a bolt wouldn’t budge with an ordinary wrench, you’d ‘get the sockit wrench’. You put a sturdy screw driver against the nut just so, pick up a hammer, get a bead on the end of the screwdriver, and SOCK-IT with a hammer: and if that doesn’t do the trick use a BFH.
Yours for more exacting and exciting English,
