Where "Big Note Yourself" Comes From
"Big note" originally referred to a large-denomination banknote — flashing one around was an obvious way to show off. "Big-noting yourself" grew out of that image, describing someone inflating their own importance the way a big note inflates a wallet.
The phrase has been part of Australian slang for decades and shows up widely in everyday speech, especially around boasting about money, status, or achievements.
"He was big-noting himself at the pub about a promotion that hasn't even happened yet."
How Aussies Actually Use It
It's almost always used critically — calling someone out for exaggerating their wealth, success, or importance to look good in front of others.
You'll often hear it about someone throwing cash around, name-dropping, or talking themselves up at a pub or party.
