Wellkiller 

A scrawny ass Chinese fag who is bullied, so he will snap at any moment and kill his whole school like Columbine. Either plays no sport at all or tennis. Usually is gay.

That kid in the corner fapping to hentai is a total wellkiller.
Don't fuck with that wellkiller or he will bomb the school.
