Do you know what this title means? First of all, it belongs to an old and very popular song written by Renato Carosone, but it has been rearranged today becoming so popular that you can dance it all over the world!
That sentence means: “You act like an American/ You wanna be an American” and it refers to all those emigrants who from Italy, especially from Naples as the song says, moved to United States and when they happen to travel back to their homeland for holidays for example, they act like “big shot” Americans who have it all, when in reality they have nothing.
