When I was a kid, we were made fun of or outright bullied for wearing glasses. Now people make a style of wearing oversized ridiculous frames (with or without lenses) regardless of whether or not they have a need for wearing them.People suck.
A normal person will like Star Wars. A nerd will tell you all about the expanded universe, his dissertation on the hidden meanings or philosophical implications of the movies, will hold the lapse in quality in the movies personally, watch more movies still, and will obsessively click on articles about Star Wars.
Also argue about the comparative tech- and power levels of Star Wars relative to other 'verses on spacebattles.com.
Calling oneself a nerd is now the equivalent of saying one is a "true fan".
Shut Up Nerd.
I'd say it's debatable that a more appropriate label for "anyone who likes something" is "geek". Obviously there's a lot of cross-pollination between geeks and nerds, but in my opinion, alongside the easily recognizable stereotypes of the comic geek and the movie geek, there are the jocks (football geeks) and joggers (running geeks) and BMXers (flatland geeks) etc. Those geeks will discuss minutiae of their particular geekdom (yards after catch, Asics vs New Balance, bunny-hops and front pegs) as fervently as a comic geek will discuss Adam Warlock's cocoon. It may just be my own personal definition, but in general I see nerds as people that are very good at actual useful things (math, computers) to the unfortunate exclusion of such things as social graces and, y'know, hygiene? Geeks, on the other hand, become fixated on completely useless trivia and hobbies, but are still for the most part able to carry on their normal lives and jobs and relationships etc. Anyway. That's my two thousand cents on the possible distinction between "nerd" and "geek".
What the hell are you babbling about? NEEEEEERRRDDDDDD!!!!!
