In study hall, literally nobody talking, and he says "What'd you call me?!"

*he then hits the scrawny kid next to him in the chest. The teacher does nothing*

In study, literally nobody talking, he says "Did you just now say you're a pedo?"

*scrawny kid says "No, i'm not a pedo". The teacher pulls the scrawny kid to the principle's office*
