Peter Goth

(the idea is not mine)
Peter is the tallest boy in your school, everyone knows him, and most people either fear him or respect him. Most girls want to date him, but he's usually disgusted by them. He's in the upperclassmen, and you're in the middle, but you share a gym class with the upperclassmen. You've never met Peter at school before, because when you were walking around, you were always in different places.
You walk into the gym for a solo workout. Peter is already on his fifth set of push-ups.
