The term "American African" is not widely used, but it seems to be a reverse of the term "African American". "African American" is a term that typically refers to individuals in the United States who have ancestors from Africa. The term acknowledges their African heritage and their American nationality. If "American African" is used, it might refer to an American who has moved to Africa, but it's not a commonly used term. Please note that cultural and ethnic identities can be complex and individual, and it's always best to respect how each person chooses to identify themselves.
