When was the first time you realized that you were fascinated by catfights?

I was quite young, maybe about 10-11 years old, when on TV they were showing some old movie of biker gangs fighting for control of the neighborhood. In one scene, two women from rival gangs faced each other in a smoky, dirty alleyway, dressed in their back leather jackets and jeans, one with a knife, the other with a chain. I remember that, at the moment they faced each other before the fight, I felt something inside me that I could not define. I was fascinated and, that night, all I could think about was the fight.
