I’m not sure how widespread it is, I think from memory the only place i looked was Wikepedia, and it said specific to Adelaide, so i guess that one’s my bad. As for how widespread it is within Adelaide i have no clue, its the only name my friend knows it by and they live about half an hour north of the city center.



I saw a more detailed instagram post about this a while back which I saved:
