nigger up
To perform live a traditional song (i.e. National Anthem) disregarding tradition and the history in which said song was written (See: "Carl Lewis" 1-21-93, or Marvin Gaye: 2-13-9-83). The Lewis version is a classic "can't sing at all" version while Gaye's 83' version is clearly "niggered up." Francis Scott Key's original version was not intended to be a personal showcase or an example of hip-hop.
