I dislike the word geek, makes me think of someone who's into comic books, anime, watches cartoons, Star wars, Lord of the rings, or Trekie fans. Have no experience whatsoever for real life events. I do non of these things.
Lately when I pick up chicks and they ask me what I do I tell them I'm a Scientist just the word makes most chicks want to jump your bones. An added plus is to be sure as to act like you smoke a tobacco pipe in your lounge chair with your suede arm patches.
Act like you know things when you talk to them throw in a few large words with each sentence of your breath, if you are not sure how to answer a question just answer it within the question. "Hmm.. That's very interesting how would you suppose that is?" "I was wondering that myself, perhaps you could postulate your views in these manners?"
I guarantee you'll get hot chicks.
