1337 is the language of hackers and newbies across the internet. Also, the words in 1337 are usually short(ie "are" becomes "r") and intentionally spelt wrong(ie "the" becomes "teh", this is most common with e switching places and o's becoming p's)

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.

A language/dialect used by to a certain extent by nearly all gamers and computer hackers. The grammar of 1337 varies, and not only are letters replaced by symbols, but there are other rules too, such as certain misspellings.
