Funny how traditions and local customs develop over time.
The area surrounding where I work is divided by a river and it is fairly easy to tell which side of the river young men come from.
As a meeting acknowledgment, those from the north say “Yo” and those from the south say “Woop”.
At local dances it is quite common for there to be some rivalry and when the inevitable scuffles break out it quickly divides into the “Wooper’s” versus the “Yoyo’s”.
I have just found this fascinating behaviour because it is not related to the usual things that divide a community like ethnic origin, religion, etc and wonder if this same sort of thing happens in other parts of the country or the world for that matter - division by a road or rail-road track perhaps ??
