A geek is a person who is socially excluded from a general population. Unlike nerds, geeks do not necessarily have to be smart. They often create groups among themselves, and generally have these similar characterizations:
-lack of participation in physical activities, such as sports
-an interest in computer
-a crude sense of humor radically different from common society
-a negative attitude toward common society.

The term "geek" originally referred to the carnival performers whose act consisted of biting the heads off chickens and eating glass. Over time it came to be applied to anyone who got paid to do work considered odd or bizarre by mainstream society.

The term now enjoys a special status within the technical community, particularly among particularly knowledgable computer programmers. To identify oneself as a "geek" indicates a recognition that most people still consider programming computers to be a bizarre act, along with a certain fierce satisfaction in being very good at their inglorious profession.

That most software geeks now easily earn twice as much as the average laborer just sweetens their defiant embrace of the term.

Note: Unlike the word "nerd," which is always pejorative, "geek" often carries a positive connotation when used by one of the group. The use of the term by outsiders is considered insulting.

The kids in high school who are considered the losers.
Ironically, those "losers" will be the bosses of the cool kids in high school, if those cool kids ever reach the same intelligence level as the once geeks(possibly not).

An inquisitive individual that handles information about a certain topic whether it is for recreational purposes, a promising career, or both.

Commentary:
A geek typically is intelligent in some manner; and is always interested in a particular topic. Geeks have social skills unlike a nerd, which is similar intellectually, yet is a socially awkward individual. Geeks also tend to be, but are not limited to, nonathletic.

People who Society deems is strange due to there love of Computers, Science Fiction, and or Fantasy.(like the lord of the rings movies) People who were dubbed geeks often get jobs working with computers or technology in general.

Someone who will go far in the future.

A Geek is a very knowledgeable person who sometimes act in a manner which can be considered odd or abnormal. They also know that they are slightly odd or abnormal and fully accept this. Because they accept this they don’t try and be normal like nerds do and ultimately “fit in” better than nerds and so are seen to have better social skills.

Geeks are superior to all other people because the have the knowledge and social ability to get to where they want to be.
