Admittedly my info is a couple decades old. When my college friends studying in Australia tried to hitchhike with their thumbs, drivers angrily returned the gesture. They were later informed that it meant “up yours” and that the correct way was to point an index finger toward where they wanted to go. Maybe years of Americans visiting have changed this.
Funny thing from an Australian friend who moved to Seattle where I live - we used to have a restaurant called Dag’s that served “Dag-burgers”. She said to her “dags” were little balls of shit clinging to a sheep’s fur. She sent home a photo of herself by the sign and her relatives thought it was hysterical.
To them “the machine” is the liberal shadow state, wokeness etc. which they think controls the world.
