Just to set the record straight, there is a big difference between being a "geek"* and being a "nerd"*.
I will admit to being a geek, but I have taken a test and proven myself to be far below the Nerd Standard.
|You Are 28% Nerdy|
You're a little nerdy, but no one would ever call you a nerd.
You sometimes get into nerdy things, but only after they've become a part of mainstream culture.
And to be fair, Hotness took the same test with even better results:
|You Are 16% Nerdy|
You are definitely not nerdy - in fact, you probably don't know any nerds.
You probably care a little too much about your image. No one will know if you secretly watch Star Trek reruns!
So there you have it.
Yea verily, we will let our Geek Flag fly, but never mistake us for being nerds.
Not to be confused with Nerd. A geek does not have to be smart, a Geek is someone who is generaly not athletic, and enjoys Video Games; Comic Books; being on the internet, and etc.
A person who gains pleasure from amassing large quantities of knowledge about subjects often too detailed or complicated for most other people to be bothered with.
Often mistaken for Geeks, who aspire to become nerds, yet lack the intelligence, and end up giving nerds a bad name due to their poor social skills. Non-nerds are often scared of nerds, due to their detailed knowledge, and therefore seemingly high levels of intelligence - and subsequently denegrate them as much as possible as often as possible.
Nerds exist covertly within the fabric of society, often choosing to 'nerd it up' in private or in the company of fellow nerds. It is for this reason they are feared the most - unlike geeks, who are easily identified, nerds can only be found out when casual conversation reaches a subject that they like nerding.
