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 ©):
A=4 /-\ @ ^ /\
B=8 ]3 ]8 |3 |8
C=( {
D=) } |) |} |> >
F*=# |=
G=6 9 (_>
H=# |-| (-) )-( }{ {-} /-/ \-\
I=1 !
J**=_| j
K=|< |{
L=1 |_
M=/\/\ |\/|
N=/\/ |\| \
O=0 ()
P=|D |* |>
R=|2 |? |-
T=7 + ']'
U=(_) |_| \_\ /_/
W=\/\/ |/\|
X**=>< }{ X
Y='/ %
Z**=2 z

Common mispellings:
the = teh
that = taht
take = taek
own = pwn
you = joo
dude = jood

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

*there is no 'F' in true 1337, it is replaced by the 'ph' phonetic in true 1337

**acceptable when not replaced by a symbol

A sub-language invented by the hacker culture during usenet days. Letters would be replaced with numbers to make it harder for non-hackers to search for conversations and pick up on what hackers were doing at the time. It got the name "1337" from the word "elite", which where what hackers were. Unfortunately, script-kiddies caught on, and completely missing the point of 1337, instead began to use it to write EVERYTHING, thinking it would earn them passage into the hacker culture. Little did they know that it actually required knowledge to become a hacker. Now it is openly mocked by the hacker community, making fun of the kids who still use it although it's more than 30 years past it's usefulness, instead replaced by 128 bit AES encryption and the like.

1. Used by both n00bs and true 1337s alike in order to convey their h4x0rz 5k1lz in a particular medium, primarily video and computer games. Its usage has become widespread, and now includes, but is not limited to, sports, sex, fighting, driving and eating. Essentially a synonym for "good."

2. An integer between the number 1336 and the number 1338.

3. The year that marked the beginning of the Hundred Years' War between two houses of the European nobility. These consisted of the House of Valois, who claimed the title of King of France, and the Plantagenets from England, who claimed to be Kings of France and England. Contrary to the implications of the name, the war lasted 116 years, ending in 1453.

2. Guy #1:I'm thinking of a number between 1336 and 1338. What is it?

Guy #2: That's easy, you fuckwit. It's 1337.

Guy #1: Unfortunately for you, I didn't specify whether the number was an integer or not. I was, in fact, thinking of the number 1336.77389.

3. My favourite war is the Hundred Years' War, beginning in 1337 AD.

The practice of using visually similar characters to replace the characters of everyday words. Many wanna-be hackers (13-year-old gamers who watched The Matrix one to many times) try to sound "professional" by talking in 1337 5p34|< (leet speak) during online games and internet forums. However, with all creatures, the ability to speak does not guarantee intelligence.

Otherwise known as 'Leet', 1337 is Internet slang that replaces letters with numbers. Mostly used by assholes in games or chatrooms who think they are above than everyone, think they can do what they like, think they are cool and think they are hackers. In real life they spend too much time on the computer, refer everyone as n00bs, have no social life and have no friends. If you think your 1337, your gay.
'leet' guy: 0m9 1 t0t411y pwn3d j00 1 4m 50 1337!!
normal guy: Stop talking in numbers you retard.
