Define "geek"

Occasionally, I come across people who do not understand why I would refer to myself as a "geek".  They seem to have the impression that this is a bad thing.  I     hear the words geek, nerd and dork bandied about interchangeably.  I take issue with this sometimes because they are very different things in my understanding or at least they have very different nuances.  

  Take  "dork" for example.  These were the kids in school that had no social skills and were stupid.  I seem to remember  these folks smelled funny.  I find no redeeming qualities in dorks.  Just to be sure that I wasn't just projecting my own biases here I looked it up:

Dork: Noun

derogatory. A dull, slow-witted, or socially inept person. vulgar. The penis. Huh.  Didn't see that second part coming.  No pun intended.

  Nerds are a little different. Nerds, especially young ones, may be a little shaky with the social skills but they are smart, sometimes stunningly so.  Nerds rule the world because we need smart people. But, still to be safe I looked it up:

Nerd: Noun

A foolish or contemptible person who lacks social skills or is boringly studious: "one of those nerds who never asked a girl to dance". An intelligent, single-minded expert in a particular technical discipline or profession

Hmmm.  A little harsher than I was expecting but close enough.  That brings me around to myself.  

I'm a geek.  A proud geek, in fact.  I think that makes me reasonably bright and my social skills are just fine.  Geeks, in my experience exhibit a little of that "single minded expert" element although generally through a pop culture lens.  We are just super-into whatever it is that has grabbed our fancy.  I once knew a "hockey statistics from 1978-1989/geek".  Weird, right? 

Oh, here is the actual definition:

Geek: Noun a carnival performer often billed as a wild man whose act usually includes biting the head off a live chicken or snake. an enthusiast or expert especially in a technological field or activity A person with an eccentric devotion to a particular interest: "a computer geek".   Yeah, a guy with an eccentric devotion to a particular interest, I like that.  So, I'm a geek.  Get it right.
