"Banjaxed. Broken, ruined; can also mean tired. "Bollocks! Me Capri is banjaxed!" "Jaysus, after that lifting them bricks all day I'm bleedin' banjaxed"..."

Kind of sorry I looked it up... I first heard it a long time ago from an Aussie exchange student who spend a bit of time as stoker. I thought her comment that her day was complete banjaxed was a complement. Wow quite a memory smasher!
