Geeks, Nerds, Dorks, Freaks, and Dweebs Defined!

Geek:
Has a purpose. Tech savvy. Geeks knew what the Internet was before it was cool. Hackers fall into the realm; if they weren't geeks, they wouldn't hack. Extensively knowledgeable in a particular fandom, usually sci-fi: i.e. Star Wars, Star Trek, Babylon 5, X-Files, and obscure sci-fi films and fandoms no one's even heard of. (Note: See for non-visual primary mediums.) Competent at video games.
Also band geeks. (Would be nerds, but how aesthetically pleasing is "band nerd?")

*A/N: I hate to break it to you, anime freaks: you qualify as geeks if you are considered an expert in your chosen fandom.*

Nerd:
Has a purpose. Somewhat tech-savvy, but prefers the good old calculator to a Pentium 4 1.5 Gig desktop. Prefers the written word to the visual stimulation, and prefers such fantasy realms, i.e. Tolkien, Moon, Weber, Drake, etc. Often participates in role-playing games. Skill with math or other technical subject often accompanies, whether genius level or not.

Dork:
Has no purpose whatsoever; offers no marketable services as geeks (technical) and nerds (mathematical, written) do. Looks funny, acts strange, not to be confused with

Freak:
Shock value. Weird for the sake of weird. High-strung artsy types can be considered freaks, as can most rock and roll stars. Smart, sometimes with closet addictions to science-fiction and/or role-playing.

Dweeb:
Retro-dork. Has no purpose. Looks funny, acts strange. For the most part, dorks past their prime, sometimes still living with parents at age forty-five. Not to be confused with super geeks.

Super Geek:
Has a purpose, but chooses not to market services. Living in parent's basement with computer rivaling the ones keeping the space program running. Hacking, playing video games, and living. Can also be Bill Gates.

Super Nerd:
College/University-level English, Lit, Math and/or Physics professors.

Obviously, these definitions apply to Generation X and EchoBoomers (Generation Y); baby boomers, for instance, have system notably different. Keep in mind that in this day of information and ambiguity, crossovers aren't unusual. It it not odd, then, to find a nerd with geek technical skills, or a freak with geek tendencies.

I'm a geek with the nerd's love of books. What are you?
