GFI
GFI first appeared in the small East Melbourne suburb of Forest Hill. First used by young man, A. Kelly, or was it Rhett or Nick? Whatever! What I'm trying to say is one of those guys came up with the word or to be more accurate, abbreviation. It stands for Get Fucked Idiot!
'Hey! I won four-square! Woot!'

'GFI, hatty! That was out, biotch!'

'What? You wanna go?!'

'Come on, bring it on mo'fucka!'
