nerd
any unpopular person who doesnt give a shit about the way they dress, or how they dont even know what the social ladder is. they dont have to be smart or anything like that, in fact, most nerds are dumbasses who get Cs and Ds and play computer games everyday. this type generally hangs out with more of its own, so you'll be able to spot a crowd. they dont have a fucking idea whats going on around outside of their little world
remember- they dont have to wear glasses

they also include people who post stuff on urban diction everyday, like me
