occa
Something or someone that’s Australian. Like if you walked into a pub and said 'G’day,' you’d be called an occa. It’s like saying someone is Aussie, but with more swearing and less sense.
"You’re not occa, you’re just a tourist who got lost," said the barman after I asked for a 'flat white.'"
"I’m occa, and I can prove it by eating three sandwiches at once."
"My dog is occa. He barks like a kangaroo on meth."
