Or was it "T for torus"? Seems a pretty bad choice, unless there was context that it was always names or something.

The informal civilian convention does indeed use given names. The names themselves are not standardized though so it's not a very good system.

I had heard B for Boris, so there's that. :)

If only there were some kind of standard of which names to give for which letter, eh?

It's a feature that you can use it without learning anything.

I always do M for mnemonic when spelling my name. A for aisle etc..

On that note, I rather like this list: https://web.cs.dal.ca/~jamie/Words/alphabet.html

AURAL

BDELLIUM

CUE

DJINN

And it gets worse!

Oh my god, this is brilliant. "S as in Serial" and "Y as in You" are two I'll definitely be using if I want to be annoying.

— "M for menemonic, I for isle", roger. — No, my name is not Roger
