Bog, toilet, loo, dunny (australian, but fuckin' funny when drunk "Hey, i'm off to the dunny").

Also, yes that's true, we say "The phone's engaged" when someone's already on the phone so you can't connect to them.


It really all depends, most people will talk normally, but if you listened to chavs or ghetto black people, it'd be all, "safe blud, wha' gwan bra?!"
