Nerd and Geek is exactly opposite in usage in my experience.

They’re on to us.

This is beautiful.

Personally I agree more or less with Girl’s definition. But the endless arguments do suggest that there is no widespread, consistent distinction.

Meanwhile, dweebs weep in the corner because they have no friends.

I wonder where crackpots like von Daniken or Velikovsky fit in this theory?

I aspire to be a nerd, but I think I am a geek. Except at parties, where I have a crippling fear that I’m a dork.

If a geek is someone who limits their knowledge mongering to tiny, useless areas and a nerd is someone who tries to apply their data to wider situations then it is possible to imagine situations where geeks are useful to have around, or where nerds end up doing more harm than good with their knowledge.

Dorks, however, are mostly always good to have around because they give me someone else to be socially awkward with.

Someone is a nerd if they do well in history class because they are willing slaves to the meritocracy.
Someone is a geek if they do well in history class because “Abraham Lincoln = BEST. PRESIDENT. EVAR!!!1!”
Someone is a dork if they do well in history class because they have nothing better to do than listen to the teacher talk.

And those (Like me) Who write fiction in history class are just plain weird.

People with strong opinions on the difference between Nerds and Geeks:
-Nerds
-Geeks

Nords and Greeks?

I’d like to get a special permit, please.
