"'Rap has really begun to get around the mainstream culture,' said Robert Farris Thompson, a professor of African and Afro-American art history at Yale University. Hip-hop words from what was once an underclass subculture are now common parlance among America's youth. 'Rappers are persons of words, and those words are getting into the language,' said Professor Thompson."
