Parking lot.

Half inch, approximately.

A cheerful goodbye.

The sort of celebratory salute which can be a toast or can mean thank you or goodbye.  Australians are a cheerful lot!

Chewing gum.

The involuntary expectoration of the contents of one's stomach into the wider environment.

What the stomach won't accept the world must accept.

The human equivalent of a bird's cloaca.

Like a broody hen, feeling a strong urge to hatch a baby.

Made a bad mistake.  These days people think it is rude but it didn't start off that way.  If you turn something up at an angle you cock it and this can be deleterious to the object if the motion was unintended.

Pronounced Coo-Wee.  The famous Australian call was developed by aborigines to be heard across vast landscapes.  Coo is a long low shout and Wee is a whipped high note.

Couple.  Americans omit the 'of', presumably because when you say 'couple of' after a while it becomes 'coupla' and it sounds like the 'of' isn't there anymore.  Or it could be American efficiency in play.

This happens when a man experiences a high level of personal excitement.

Flirt with intent.

Flatterer.

Hard red ball which is thrown at the wicket in cricket games.  Smaller and heavier than a baseball.

Australian exclamation of surprise.

It's had a price cut!  Cut-rate, discounted, on sale…
