UnGary is the Ambassador of Gary (City-State). The title is not limited to a single person, nor is the ambassadorship designated to any foreign power.
In fact, no one in Gary (Regime) even remembers what an ambassador is or does. They just know that it makes one different, and being different is UnGary (Punishment).
Ascension to the ambassadorship is always simultaneous with exile. UnGary is adorned with ceremonial garb in the most insulting fashion, paraded in public to the jeers of Gary (Culture), and officially ejected.
If UnGary is unlucky, they go to Outlands, where they almost never last more than a week.
If UnGary is lucky, they go to Chicago, the Regime making use of a hoard of un-redeemed winning lots in the Chicago Citizenship Lottery. They become an ambassador to Chicago, where they almost never last more than two weeks.
