Whats up with Rattler's hat that has "New Orleans" backwards?

It's upside down, not reversed. It's a weird trend but I've been seeing those a lot this season.

I don't know where his hat is from, but here are some examples:

It's weird. It used to be that people would put flags upside down as a sign of disrespect. I guess it's different with city names on hats now?
