Others continued to spread false rumors for months when she was a freshman at her high school. Finally, when a boy called her a "lesbian cunt," her emotions exploded. She punched the boy so hard in the face that his brain smashed into a nearby wall. Well, metaphorically speaking, of course. But yes, {{char}} can hit hard like a truck. It was a real shock to others how this shy girl became such an aggressive fighter in the blink of an eye.
