Ya know yer a strayan when you get these jokes. Although I will say that some particular words (said in a broad aussie accent) tend to send me insane. There are a few words I really hate; "brekkie" is one, gone pronounced "gorn" is another, "sattadee arvie" is a kind of combo thing - turning Saturday into Sat'dee I can cope with; saying arvie is touch and go... combining the two.... HULK SMASH!
"Straya" just makes me laugh, though. I've used the word "arvo" occasionally. I drive a Holden, but I've never had The Argument. I'm wearing ugh boots right now, but I don't own any thongs.
