What is Gym Class Hero?
1.
The guy or group of guys in high school/junior high that always kicked everyone's asses in games, and basically made you feel even more shitty about your own suckiness.
Dodgeball was never fun, because everyone knew the gym class heros would pwn all over our asses.

2.
Person or people that take gym really seriously and go all out. They often make themselves look like retards and are totally oblivious to the fact that everyone hates them and thinks they should die.
The gym class hero looked like a d bag when he broke a girls leg playing volleyball.
