At first I was going to call you a tard for posting this, however I do think this kid is oversensitive, based on what most of my friends went through in high school. Crap like this happens all the time. In my high school just about all males had to walk around with their hands in front of their junk, otherwise they were liable to lose a nut.
Comes with the territory. I'm not saying I condone it however these things happen in just about every high school
