True Blue is technically a term from the UK meaning genuine, but taken on by Australians to mean Genuinely Australian. Made popular again in the 1980s by John Williamson's song "True Blue" which we do not recommend you listen to as it will get stuck in your head forever. Dinky Di and Dinkum also mean "the real thing". "Fair Dinkum!" is a term used to mean "Really?" to emphasise or seek confirmation of the genuineness or truth of something.
No matter the relationship, any two people could have a blue – be it a physical, verbal or emotional fight or argument. A blue can range from something minor to a "Major Blue" which might end a friendship.
Bloke is used in other Commonwealth countries as well, but in Australia, a bloke is a unique masculine archetype associated with our country's national identity. The "Aussie bloke" has been portrayed in important works of art and associated with famous Australian men.
Goon or Goon Bag is wine that is sealed in an aluminium bladder with a plastic tap on it which is encased in a cardboard box. It most commonly comes in 2 or 4 litres casks – the 2-litre being the more classy of the very non-classy wine. A common game at Australian backyard parties is called "Goon of Fortune" where you peg the goon bag to a Hills Hoist (rotating clothes line), spin the clothes line and whoever it lands above, has to scull straight from the bladder of wine. Once you've emptied the bladder of wine, it can be blown up with air and used as a pillow when camping.
Cockney rhyming slang used the term "tin lids" or "saucepan lids". Australians use Billy Lids in reference to a billy, which is a lidded pot used to cook on an outdoor campfire.
A British slang term but often used in Australia. Blower comes from a mechanical precursor to the telephone, the speaking tube, each end of which was stoppered with a whistle. In order to attract the attention of the person at the other end, you took out your stopper and blew down the tube to make the other whistle sound.
