fo'sh 

Basic meaning is "definitely". Shortening of the term "for sure".

Typically used when genuinely excited, so usually accompanied by an exclamation mark.

Originated in early 2009 within the pseudo-indie-bizzaro-trendy scene in Perth, Australia.

Note on pronunciation:

"Fow-sh", where "fow" is like in "bow and arrow", not "fosh".

"Are we on for tonight?"
"Fo'sh!"
