For all those people across America especialy the ones in the north, that arent spanish speaking. The spanish word "Chiva" corectly said, refers to the goat meaning chiva. Mexicans especialy are familur with the "tres animales", refering to "mi chiva, mi gaillo, y mi pedico" This means my goat, my rooster, and my parrot. These three animals represent heroin, marijana, and cocane, and there names are used as slang for those drugs especialy in SoCal. Chiva/goat = Heroin, gallo/rooster= marijana, and pedico/parrot= cocain. So now you all know what the real meaning of things are. There is even a song from some mariachi band that elaborates on it.
