Like squidz said, it's more from when Edina was upper class and the other schools were lower or middle class. Like Caddyshack...upper class snooty folks vs the middle/lower class common folks.
Of course nowadays it's way different and most of the suburbs are all upper/middle class, mostly white, pretty much everyone's the same. So it's funny when say a Minnetonka kid is trying to tease an Edina kid but both of them are relatively rich white kids
