The wanna-be nerd, for instance, will have nothing to do with fantasy, role-playing games, and science fiction; in fact, they may actually be unable to tell apart such great examples of nerdy sci-fi as Star Wars, Star Trek, Battlestar Galactica, and/or Doctor Who.
Bob: "No way, man, he's just a wanna-be-nerd...he spends all his time blogging about his baseball cards and he's never even SEEN Star Wars!"
Wannabe Nerd: Oh, what a waste of precious time. My education means far more to me. I shall spend the night reading non-fiction. I guess I just like nerdy activities, too much...
(no, not really. I'm just saying that because I know you're smarter than me and it pisses me off).
Bob: No, he isn't. He's not smart at all, he just skips school to play LoL all day. He's just a wannabe nerd.
