Hahaha that's quite funny.
It must be my Australian linguistics, it is to my understanding that it's staff in America and other countries but since I was little it's always been stave.
I have no idea if you're American or not but hey.
Other words you might find confusing from the Australian dictionary:
Boot - Trunk (like in a car)
Biscuit - Cookie
G-banger - Thong
Thong - Sandal I think? like on your feet at the beach shah.
Then there's the many synonyms for beer, hello, friend, not-friend, urination and female significant other, which are all very.. inappropriate for an internet forum.
