Usaian 

A citizen of the U.S.A.

Because citizens of the U.S.A. don't have a proper name for their country, only a designation of their location, they should be known as Usaians. Every person on this hemisphere is an American. Citizens of the U.S.A. deserve a special name because they are special!
