What's the difference between geeks and nerds?

I like how you said "hey, my boyfriend is a geek" as if to say only males can fall under this genre of people.

My opinion, a geek excells in one subject or task, geeks are more hands-on, do more physical work. A geek might very well fail in school yet be a complete genius in some area.

A nerd is someone who tries to learn about every subject, act like know-it-alls, lack practical skills and often aren't as smart as they think they are. Tend to not have a sense of humor. Not much creativity.

I always see nerds as people who have marginal interests and who know far too much about it. Also people with social skills a bit lacking. Geeks, to me, are people who have skills in broader subjects, like science or computing and may have better social skills.

nerds are book smart and geeks are computer/gaming smart

I saw a Venn diagram that explained this pretty well.

My work here is done.

A nerd is someone who is like book smart, or a know-it-all.(i hate to admit it but i'm a nerd.) whether the nerd has social skill or not depends.
A geek is some one who IS socially awkward. you know, the guys that are way into comic books and the like.
(personally i think geeks are cute)

A nerd is a smart geek. A geek is just really geeky.

I went and looked both up from 4 different dictionary sources, noted each's etymology, and then sourced three opinion blogs!

Pop quiz: which does that make me?

I think geeks are the better ones and nerds might be the stereotypical ones who snort and play runescape all day.

Nerds are the smart braniacs losers, geeks are the flat-out losers.

does it really matter?

I've only recently discovered that I'm not a nerd any more. I used to be nerdy about many things, and I still think of myself as a nerd, but all the things that I used to be a nerd in I'm not interested in now. This is frustrating, because now I have poor social skills *and* no deep knowledge of anything specific. Because of this I fit in poorly with almost any group, nerds or otherwise.
