Same here, I was a fat pudgy kid in high school. After being tormented daily from seventh grade onward by a particular group, there was one day the high school quarterback and a few other football players decided to throw water balloons at me in middle of January. Of course, they got me with about six of them, soaked my backpack, and school work.
I. flipped. out.
All I remember was walking very calmly towards the quarterback and punching him in the face repeatedly, he tried to hit me but I grabbed his arm and bent him over backwards and just kept punching until he started bleeding from his eyebrow. His friends pulled me off and then threw me down and started to kick me, but it was broken up. Sure I got suspended, but that group never picked on me again.
As a counter point to the football player thing, I lifted with a lot of the O-line guys in college. Most of them were comic nerds, and a handful played Warhammer 40k.
One of them straight up asked me: "I'm coming at your base with two rockvees and an ambo - you've got a Jarmen, two scorps, and a quad. What do you do?"
To be fair to the those unfortunates who were not on the offensive line, I actually got recruited to dungeon master by/for a bunch of the star high school football seniors when I was a sophomore. I want to say there was a quarterback, a running back, and a linebacker involved, but it's been long enough I don't remember all the details.
It's certainly true that our offensive lines were usually at least half national honor society members -- there was always significant overlap with the quiz bowl team -- and we had at least one hard core geek each year. It wasn't at all unusual to find two of us trying out the latest RPG or swapping indie B&W comics.
