All I can think of is language and Australian sayings that may not be heard anywhere else (perhaps that's a good thing!) This list goes on forever, my apologies (yes, we say sorry way too much too, must be a colonial thing, sorry!) 😎
When "have a good arvo" draws a blank stare. When is the rest of the world going to get on board with the endless list of Australia's very excellent everyday phrases?
"She'll be right"
Because there's simply no better way to let another person know that everything is going to work out just peachy, so turn that frown upside down.
Here's a fact: Our American friends have no idea what a shout or a round is. But they really should, for the sake of our bank accounts.
"Chuck a sickie"
This one is up there with "bludging". On second thought, it might be a good idea to keep these phrases to ourselves. You never know when you might need to call in a mental health day.
"Spit the dummy"
Because we all need to be able to call out a grown man or woman when they are having an unnecessary tantrum and embarrassing us both.
"Carrying on (like a pork chop)"
Conveys so much frustration in just two words.
"Have a good one"
Usual response to this friendly farewell tends to be, "have a good what?" I'll never tell.
There really is no replacement. A redneck? An uncultured person? It's a cracker of a word though.
"Taking the piss"
Admittedly, we've nicked this one from our British chums, who enjoy a bit of lighthearted ridiculing as much as we do. Americans, not so much.
"Have a crack"
Challenge: go for the trifecta with something like, "No worries, I'll have a crack and let you know how I get on." Enjoy the blank stares that follow.
Any Aussie will tell you there's a distinct difference between "yeah, nah" and "nah, yeah".
Because we're lazy AF but we still want to thank you, kind sir.
"I'll suss it out"
"I'll investigate so as to determine the correct answer and will report back in a timely fashion."
Also bowlo, bottlo, garbo, barbie, brekkie, mozzie, servo, tradie, cozzie, Macca's (am I missing any?)
"Throw a shrimp on the barbie"
Said no Australian, ever (prawns maybe). Write that down.
To be fair, there are heaps more. (We say heaps a lot, too). 😁
