these people most likely just chose that location because they think that's funny or smth.

I can't speak for everyone but I am a dirty memer, so that's why I set my country as Antarctica.

In reality I'm just a nerd from the US but that is so much more boring.

Antarctica doesn't actually exist. It's a myth made up by elitists to try to hide the truth about Santa Claus. Everyone knows his sleigh is pulled by penguins. Deer can't fly, but birds can. It's so obvious. Open your eyes sheeple!
