i think its instinctual, because it goes beyond race, culture and gangs. one time there was this bitch staying at my boyfriends house. i didnt like her because of a few reasons, but i think the main reason, is because it was my mans house....i.e. my territory. i didnt realy have a reason not to like her, but she made me feel hella uncomfortable. after she moved out, everything was cool. i think it was the simple fact that there was another bitch in my territory.
