Fight for Freedom. The "FFF" was a "gang" of basically what would now be called emo white boys in the San Fernando Valley ("The Valley") in the 1980's. FFF stuck together for a while (security in numbers) during the time when "real" Mexican and Black gangs began to take power in Los Angeles. FFF faded away as everyone grew up. White-boy gangs never really caught on in Los Angeles.
