From the Wonder Of Whiffling (And Other Extraordinary Words In The English Language) by Adam Jacot de Boinod, a few Australian entries in Best New Words Of The Decade :

barbecue stopper : an issue of major public importance, which will excite the interest of voters

flairing : the action of bartenders balancing, catching, flipping, spinning or throwing (bottles, glasses, napkins, straws) with finesse and style

dog-whistle politics : to present your message so that only your supporters hear it properly

flashpackers : intrepid, but comfortably-off travellers

That's it? That's all Australians have contributed to neologia in the first decade of the 21st century?

Commenters here rip the full list to shreds, and come up with many, many better and more widely used 'New Words.'

As far as new words from around the world go, it's downright criminal 'Fucktard' didn't make the list.

'Meh', as used by Lisa Simpson (meaning bored, unimpressed), however, did make the list.

So it's not all bad.
