Writing on Australia Day, it is an appropriate reminder that Plain English means avoiding slang terms that readers (particularly on the international forum of the Web) may not understand. This doesn’t mean you can’t marvel at the colourful colloquialisms human beings have created. Have a look at the Australian Slang Dictionary. I particularly like the entries under Y, which include yabber (to talk too much), yabby (a small freshwater lobster/crayfish), yack (to talk), yakka (hard manual labour), and yarn (to have a talk or discussion with someone). Very confusing to those not in the know!
