I do think to an extent violence can excite a girl, but it depends on the girl and obviously the type of violence. It is exciting because a girl's primal instinct is to look for a mate who can protect her and get aggressive if her security is in jeopardy. So in an way, that type of violence can excite a girl. If I were you though, I'd stick to throwing punches and following through with winning and actually kicking the guys ass. Seems by your description that you were owned in front of this girl.
