This is the first time that I've ever heard any music group suing the government over identifying their fans as gangs. In relation to the term homeboy/homegirl being defined as a term used by gangs, I suspect that this is a direct influence of corporate or government agencies. The term homeboy and homegirl was by and largely used by African-Americans who left the south during the Great Migration to identify people from their hometowns or locales. In later years, the term was used to define a person who you knew from around the way or were cool with. This other business is nonsense.
