This reminds me of a conversation I had with someone from Wisconsin.
They called be a “Fib”
It stood for “Fucking Illinois bastard”
They were amazed I had never heard of it. They use it all the time when they see our license plates ect.
I told her “That’s crazy…. we don’t have a word for you…. You never even cross our mind.”
That’s how Americans feel about the rest of the world.
