I didn't read the thread at all, but you rustled my jimmies with this nerd talk.
Nerd, as people born in the early 90s and before knows it, is defined by their ability to do well in school and play DnD and similar stuff. They are social outcasts BECAUSE they are shy, 'weird', and they just don't know how to socialize. Clothes also tend to sway towards the simple and comfort side, with just jeans and some t shirts. They also can't get good jobs/girlfriends/what have you until they hit their twenties and are forced to socialize with people that use them in college. It's a tight knit clique, just like all the high school cliques.
You, however, are not a nerd. You are smart, I will give you that. But unless you play DnD or watch some sci fi show religiously, you are not a nerd.
