"Jang", slang for good

I didn’t make that up, did I? I just used it to my daughter as slang for “good, great, nice, etc”, and she accused me of making up words. I’ve gone to the almighty google, which doesn’t come up with any results with my meaning, but…I’ve used it that way for years, possibly decades…I know I must have got it somewhere. Anyone else remember it?

What Urban Dictionary has to say.

Damn, after perusing the Urban Dictionary entries, you should consider yourself lucky that your daughter thought it was a fake word.

I’ve hear ‘nang’ being used to mean ‘good’.

I can’t get Urban Dictionary at work. Didn’t it come up in *Wayne’s World *(movie) as Cantonese for “excellent!”? That’s where I picked it up anyway. Zang!
