Worldian

A person who considers the whole world as his country and home. This person does not have any patriotic feelings for the country he lives in. He does not distinguish another human being by their differences like race, culture and religion. It is similar to cosmopolitanism but slightly informal.

Person A: My mom's American and my dad's an Indian!
Person B: What the fuck is American and Indian? They're humans aren't they? I do not know such terms, I'm a worldian!
