look up any word, like hipster:
The person who is called a loser because they are surrounded by stupid people.

A smart person who has both technical and social skills. Not to be confused with nerd who has technical skills but only has those technical skills because he has the time from not having friends or any form of a social life.

n. a book-smart person who is attractive and generally well-liked. Not to be confused with nerd (a book-smart person who is not attractive -or doesn't keep up his/her appearence- and usually a social outcast) or a dork (does not have to be smart or popular, just used as a silly insult).

The modern interpretation of geek is someone who has a strong interest and enthusiasm towards a particular generalized subject, or a specific segment of that subject. There is no restriction on the types of subject that would qualify someone as being a geek on that subject. The interest may be strictly observational, but could also be participatory.

A "nerd" is sometimes used interchangeably with "geek". But more accurately, a nerd is a type of geek (commonly, but not entirely, restricted to interests involving academics or fantasy) who has difficulty communicating coherently with others outside the realm of their own interest.
The subject of a geek's interest can be absolutely anything, such as cars, video games, live theater, movies, music, technology, etc. Or the interest could be focused on a specific segment, such as a type of car, a style of theater, a genre of movies, a style of music, an area of technology, etc.

A music geek's participation, for example, may be limited to just watching musical performances, or actively playing an instrument.

The largest, and most vocal, collection of people who have a strong interest and enthusiasm towards a particular subject would be sports geeks.

a person who honestly could not possibly care less what is "cool" or what people think about them.
If they like something that no one else is interested in (books, tumbler, doctor who) they will proudly display and talk about those things.
Not to be confused with a hipster... Hipsters try too hard.
Bob's love for shakespearian insults really brings out the geek in him.
