Get up and fight her.

You are sick of being pushed around. You don't care if she is a girl. You grab for her legs, but she easily evades you and aims a solid kick right into your groin, leaving you groaning with pain.

"Remember what I said, sissy," Rachel says and strides off. Two other girls who had been watching turn and leave when she does, walking behind her.

You stay on the ground for a bit, clutching your groin, embarrassed and humiliated that you've just been outfought by a girl. You notice that everyone around you is studiously ignoring you and you pick yourself up and continue on your way.
