I didn't know that people who weren't from fiji could read this blog. Well, obviously i knew, but it never occured to me to explain the meanings of some of the slang that i use :P (apologies to the american friend and other non-pacific islanders)
First off, Wilson of Paradise Fiji Blog has a regular, slang of the week feature, which is quite handy if you want to be "in with the cool kids slang". Waaay back in october of last year, he did a post explaining the term "leva".
Also, here is a picture i put together a while back. Hope that clears up some confusion ^_^
