How do you spell 'zjoo-zjing' (?) ?

Hi,
This is one word that gets me stumped. I hear it all the time on TV and radio, but unfortunately not in newspapers, so I don't know how to spell it! I love in Australia, so maybe you don't know of. It means getting spruced up, beutifying yourself, things like men putting tips in their hair; dying their hair; things like that. I've got a few ideas on how to spell it (zjoozjing, Joojing, ghuughing, ghughing, ghuzzing), but they're probally all wrong, although the first one may be right. I hope you understand my question, because as you probally know, it's hard to ask how to spell something on the internet when you don't know how to spell it!
Please reply if you know,
