I did sound for a band that kept asking me to turn things up/down a 'moo'. I realized (months later) they were saying 'µ'. Damn band-speak.

but isn't that letter pronounced like "mew"?

at least they're not saying stuff like "can you make delta backing vocal volume equal a small negative?" or something like that. I promise to use that phrase if we ever play a show at some school-based venue at MIT

I've heard and hated, "Gnats Cock" eg, "Can my vocals come up a Gnats Cock".

Pretty shocking really......

I've always used either "tip" or a "schmidgle."

One time, my literary nerd friend told me to take the bass down a Beckett and make certain the kick was Joycean. I liked this but it has no real practicality about it.

not sure if anyone's said this yet, or if is just an Aussie thing, but sometimes we will hear:
"can ya turn down just a bees dick mate?"

meaning: a minute amount please.

I just gesticulate wildly until some man appears and turns the dial on my amp.

A "cunt hair". Always.

Nicely done sir.

Oh! Another one...

'Can you turn the guitar up (squints, bunches up face, thumb and forefinger an inch from each other)... this much?'
