How do you spell this word? Or does it even exist?

[jalopy]

That expression to 'juche, juche' it up, like enhancing or making it something more than it is.
I hear it being said but is that how you would spell it?

Over to you.

Juice?

do you mean juju (means same as your def.).

No, not juice, more like 'juj, juj'. Difficult pronunciation to describe. It's probably a made up slang expression.

I always presumed it was a French word.

I know the word you mean - damn difficult to spell. Joosh?

I know what you mean too- like a french person would pronounce juj.

Yes, lynette, it has a french sound to it.

jeu jeu?

Hmm, jeu is tranlated as a game or diversion. Not sure but good guess.

I had never heard it before Queer Eye for the Straight Guy. I've never seen it written down, but if I had to guess I'd say zhoozh.

Zhuzh?

It's zhoosh see here

I don't know how to spell it, but I have always assumed it was a Yiddish word, llike so many incredibly apt colloqialismz - like chutzpah!

Well done, I think it must be zhuzh or zhoosh.

Heard Brix Wotsit say it on Gok's programme this week.

zhoosh, it's a polari word.
