Leet translators are laaaame.
Leet speak has an interesting take on the common convention of tenses, ignore them entirely! Now, actually, this is harder than it sounds, since a literal transliteration in leet of ?He ran to the shop and washed the dog.? is ?He runs to the shop and washes the dog.? But this will become more comfortable over time (you'll never use leet to talk about shops or dogs anyway). Quite simply, it's an easy rule to obey, but if you don't, you'll be spotted instantly, and ejected from the forums as a person of common intelligence. One more thing to remember: Capitalization is optional. It may not happen at all, or could quite possibly run rampant. And don?t be surprised if a random letter is capitalized in the middle of a word or sentence.
Here is a list of the most commonly used words found in leet speak:
0wn3d - One of the most popular l33t words it is very loosely defined as beaten or can simply be an expression of awe, for example, 'I 0wn3d you' means 'I have beaten you in a very humiliating fashion', or '0wn4ge!' which means 'That was (or is) very nifty'.
w00t - Derived from 'hoot', this is defined as 'yay', it can be used, for example, upon victory or, possibly, the release and procurement of a new video card.
ph33r - Fear, most commonly used in such phrases as, 'Ph33r m3!' or 'Ph33r |\/|y 1337 sk1llz!' It can also be written as, 'ph34r'.
sk1llz - Obviously derived from 'skill', referring to skill in some type of online game, programming or hacking. Many times used in conjunction with 'm4d'. As a general rule, if one has sk1llz, one is to be ph33r3d.
m4d - Mad, mostly used as a descriptive term meaning great, for example, 'h3s g0t m4d sk1llz'.
j00 - You, commonly used in such phrases as, 'j00 d34d f00'.
f00 - Fool, one who isn't very bright or skillful.
j0 - Yo, as in the greeting.
d00d - Dude; an expression of comrade, or just used to address a random person online.
sux0r - Sucks, as in '7h1s sux0r', one of the few common examples of the -0r clause.
n00b - Short for noobie, misspelling of newbie; someone who is new to something, or just not very good at it.
This list is not comprehensive by any means, as the limitations of leet-isms are only restricted by imagination.
General rules however state the following:
A: 4 or @ (4 is the most commonly accepted.. @ is acceptable ONLY at the begining of a word)
B: 8 or 6 (Use 8 exclusively unless you intend to not use 6 for g)
C: C
D: D
E: 3
F: F
G: 9 or 6 (Often 9 or 6, but be warey if 6 is being used for b)
H: H or # (Very rarely is it #)
I: 1 or ! (1 is most common, but where L is used, ! is acceptable)
J: J
K: K
L: 1 or | (1 is the most acceptable)
M: M
N: N
O: 0
P: P
Q: 9 (only where g is represented by 6)
R: 2
S: 5 or $ or z (Only ever Z at the END of a word. $ is VERY uncommon)
T: 7 or + (7 most common. + only acceptable in a 1:5 ratio with 7)
U: U or V
V: V or U
W: vv or W
X: X (ONLY capital, usually)
Y: Y
Z: 2 or z.
As I said, I don't beleive lines, slashes or other ASCII belong in Leet.
