Re: Slang. I want it.
Speaking from New Zealand, I hear a number of these around - bro, swag, etc. - but we also have an extremely common one which I haven't seen mentioned yet. The usual slang term here for 'you' is G or gee or however the hell you spell it, pronounced as in the letter. Example uses include "You wanna fight, G?" and "Aw na, G, we're coo'."
If I creep into your house in the dead of night and strangle you while you sleep, you probably messed up your grammar.
Ignis Equine by Akrim.elf, may that name be famed forever.
