Around 2005-2007 "Libres y Locos", Tigres firm, were called "Negro" by their neighbor rival firm, La Adicción (Monterrey). Tigres supporters are normally associated with popular or poor sectors of the city while Monterrey Club fans where associated with "wealthy people" or high class citizens. Negro was an insult but did'nt have a racist connotation. It was a imported concept from Argentina where people who listen to Cumbia Villera (working class people most of them) where called "negros cumbieros" (Negro mean black and cumbiero its and adjective to point somebody who like cumbia) by the high class society. Around this years Libres y Locos started taking Cumbia as their main Firm music and started calling themselves as "Negros" to show their rivals that they actually like the new nickname

Como on black, come on black, come on black, Como on black, come on black, come on black, I am down with San Nicolás crew, Following Tigres wherever he goes, Tigres we will never fail on you, This supporters really stand their ground, Thats why I come and cheer you, We will never fail, You're in my heart, We're the bosses of the grandstand...
