Aussie slang

Budgie smugglers... (men's swimming trunks)

The very talented John Murray illustrates the term PERFECTLY!

 A mouth like the bottom of a cockie's cage... (dry mouth, particularly when hungover)

Dunny documents (toilet paper)

And other such phrases that are causing our current exchange student much confusion and hilarity (particularly the budgies, as her grandmother has pet budgies!).

I love Aussie slang, it's versatile, humorous, clever and irreverent, all the best things about Aussies.  It can also be impenetrable, head-scratchingly obtuse, rude and all kinds of wrong!
