Never mess with a girl in a bathroom. Especially if that girl has a black belt in taekwondo.
The girl was in the bathroom of her high school in Carmel, Indiana when the male student came in with a knife and tried to attack her.
She was able to defend herself against the attempted attack and take away the boy's knife.
“I’m no hero. I just resorted to what I learned,” she said.
Neither student was identified by authorities.
