How to Speak Australian

I've picked up quite a bit of Ozzie slang while here:

No worries = No problem
Bits = Stuff
Potato Gems = Tater Tots
Pissed = Drunk
Taking the Piss = Making Fun Of
Tomato Sauce = Ketchup
Beetroot = Beets
Hungry Jack's = Burger King
Maccas = McDonalds

Tonight after getting pissed, we went to Maccas (which I thought for a while was Mackers), which is apparently ritual here. Everyone there seemed to be drunk. Since I normally hate to have food I can eat at home, but nothing else was open, I tried something new. The McOz has a slice of beetroot on it. It was quite good. Almost got into an altercation with some idiot who corrected me when I said ketchup. I told him to bite me, and he followed me around the store asking if that was a invitation, promise, or threat.
