An elitist. Usually found within the college community. They seem to think they are better than everyone else in most every way. They like to hang out at coffee shops while talking about fashion and philosophy. They also enjoy reading dictionaries so they are able to use a more sophisticated vocabulary. They laugh loudly at smart jokes so you know how intelligent they are. Don't expect to greet one of them and be accepted into their group.
Look! He looks so indie with his scarf, cap, and sweater. Oh, and he's holding a book in his hand and laughing pretentiously. He must be 1337.

Me: Hey what's up guys?
1337: Oh nothing, just examining the dictionary so I can use a new word in a colloquy today.
---
Me: What are you doing?
1337: Looking in the mirror to make sure I look as smart as I sound today.

A 1337 joke.
1337 #1: Descartes walked into a bar. The barman asked "Would you like a drink?"
To which Descartes replied "I think not!", and vanished.
1337 Group: !!!!!BAHAHAHAHAHAHAHAHAHA!!!!! (making sure the entire coffee shop hears their roar of laughter to make sure that they are seen with the other 1337'2)

the term 1337, also "leet", is used to describe somthing of excellent quality "this pwnage is uber 1337(leet).
This is a language typically used in internet gaming and some people stereotypically this its only used by a select few called "Nerds".
But, leetspeek, also leetspeak is used pretty much by all internet gamers and is not in any way a "Nerd Term"
as some call it.
"He is so 1337"
"Man that pwnage was so ubern 1337ness."
