Aussie Words & Meanings
Banana Bender:  The term derives from the joking notion (as perceived from the southern states of Australia) that Queenslanders spend their time putting bends into bananas. 

Barbecue stopper: A topic of great public interest, especially a political one. The term derives from the notion that a topic is so interesting that it could halt proceedings at a barbecue - and anything that could interrupt an Aussie barbecue would have to be very significant indeed!
