I'm so happy that all this Nerds Vs Jocks is just an U.S. thing. In the rest of the world kids go to school to, you know, study.
In the my high-school equivalent there was a football teams, but they weren't considered demigods by the rest of the school, and the girls weren't dying to sleep with them just because of their ability to throw a ball at goal. And a couple of them were even borderline nerds! And if I remember correctly, someone also gave up the team because it took time away from their studies.
Nope, not a US only thing. It happens all around the world and i was bullied to back in school. Teenage boys and girls can be dicks all around the world.
