[gronglo]

It's still offensive in Australia, and is mostly used as a pejorative term. It just carries a lot less weight than it does in the US, and is not strictly used to refer to women.

It can technically be used as a term of endearment, especially if you add a word like "sick" or "mad" on the front. But it's still a bit crass. You're more likely to hear it used among a group of drunk friends or teenagers than at the family dinner table or the office.
