Can't tell what the initial offense was. A possibility is that he snuck in a quick inappropriate goose (or she thought he did) when he squeezed by her and that is why she turned to face him. I can't see or think of anything else that would cause her to react that way. Only the two of them know what really happened to cause the confrontation. Regardless, it is not cool to punch a girl. Why are these exact same kind of incidents happening with regularity with FSU football players?
