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 mostly complete translation chart(exluding unicode characters, ie ©):

Common mispellings:

dude = jood

common phonetic replacements(always used in true 1337):
f = ph
ck == xx

**acceptable when not replaced by a symbol

Pronounced "Leet", short for "Elite". The original phrase was 31337, or "Elite", referring to the best hackers. It is still used today by some of the good hackers, but the word has been picked up and overused by so many losers and posers that its meaning has been corrupted.

usage: most commonly used for people who don't know what 1337 is about and think it is cool

it was actually used in usergroups where content including things such as "hacker" were censored or deleted using programmed filters. using 1337 was used to get past these filters and since there are so many forms of a word using 1337, they had to give up.

A word used my losery 10 year olds who read it playing Counter-Strike, which is in between watching Dragonball Z and Pokemon. Most of them don't know what it means and write screwed up sentences.

Leet//1337: (most commonly 1337 but often also leetspeak, leetspeek, l33t5p34k, or l33t) from the phonetic form of the word "elite", is a cipher, or novel form of English spelling. It is characterized by the use of non-alphabetic characters to stand for letters bearing a superficial resemblance, and by a number of spelling changes such as the substitution of "z" for final "s" and "x" for "(c)ks". Leetspeak is traditionally used on the Internet and other online communities, such as bulletin board systems. Leetspeak is commonly used by hackers, crackers, script kiddies, and gamers.
----However, leetspeak is not popular amongst all hackers. Many consider it a pointless affectation, and as it has become widely used it is less useful as a way of showing membership of an "elite" group. It is nonetheless a cultural phenomenon well-known amongst hackers and many other Internet users.
----Certain factions maintain that "true" leetspeak is spelled correctly, with the exceptions described above. They do not consider the use of extreme short forms (such as "b" for "be", or "u" for "you") as leetspeak; instead, they refer to it by such terms as "AOL speak". This is because they associate such habits with users who use ISPs like AOL, which is associated with "newness" and therefore not considered "elite". Another convention sometimes associated with leetspeak or Internet chatting is capitalizing every other letter (LiKe ThIs), sometimes called studlycaps or stickycaps. A similar habit involves capitalizing every letter except for vowels (LiKe THiS).
There are two kinds of people in this world, noobs and leet....4nd 1f y0u c4n7 und3r574nd 7h15 7h3n u r 4 n008

A language used by hackers and posers alike, it began in 1993. In that year, only the lightest 133t was used by hackers, just enough so that their web sites would not be found in a mainstream keyword search. For several years, it went on like this, and was relatively unknown.
Then, with the release of massive multiplayer online roly playing games (MMORPG's), a few hackers began to play, and they used l33t in the game's chat system.
Now, several years later, l33t has permeated the entire Internet, being used both by those who are truly hackers, and people who use what they pick up.
133t comes in several rankings, starting at light l33t, up to hard 1337, and finally ending with ultra |_33¯|¯. There is also something that I will not try, and that is known as 'uber l33t,' in which neither letters nor numbers can be used. This is reserved to only the truly great, and almost requires a modified keyboard.
