Explanation: Definition: His Stars and Stripes is typically American
SO US. There's a story to the effect that John Philip Sousa (the "March King", composer of "The Stars and Stripes Forever") was originally called "So", and that he added "USA" to the name for patriotic and/or commercial reasons (various other versons of the story also exist), but there is no truth in it.
