Actually, I agree.
Back in the 1970s-80s, the word was "Westie" throughout NSW QLD, and non-city Victoria… but then a TV show produced by a Melburnian Investment Banker had a character who said the Melbourne-Kew area word "Bogan" all the fucking time. After 5 years, people who didn't interact with their communities much used "bogan" like they thought /everyone/ knew it. 20 years later, it's fucking used on slack-social websights like Reddit, along with Steve Irwen worship, VB beer, "straya", etc.
Likewise, "cunt" is another affluent-area Victorian thing that social media products use instead of their actual local area lingo. My area of Newcastle used "tard" when I was growing up. Western Australia mostly uses "cheeky". Using "Cunt" is a red-flag you're a programmed tard.
