Many people will argue that it started with the popular game Counter Strike, but X's def. is the most correct. According to "The Hacker Crackdown" by Bruce Sterling, it was an invented language used to confuse FBI and NSA sniffing programs during Operation Sundevil, when the government placed "wiretaps" on the Killer server to find hackers. Used extensively after the E911 document scandal and the theft of Korn 78 and other UNIX programs by AT&T. Google "Fry Guy", "Terminus", "Gail Thackery", "Acid Phreak" and "Phiber Optik" for more information. Discontinued among true hackers thanks to encryption engines and PGP keys.

There are two varieties of 73h l337. They are used based on the respect carried towards the person whom you are talking to.

l337 Light is used when you're talking to friends, acquaintances, and family because it is merely casual talk.

Hardcore l337 is when you are talking to a person of higher importance or someone you respect and/or admire greatly. Unlike l337 light, which is an alphanumeric language, hardcore l337 utilizes various other symbols.
l337 Light:

h3y d00d. h0wz j00r m4d g4m1ng 5k1llz?
hey dude. How are your great gaming skills?

Hardcore l337:

Online Language. Because the standardised version has been lost or ignored or never invented, many dialects have appeared. While there is grammatical and spelling differences, it is almost identical to English to the point of being a mere substitution alphabet, and is rarely used in other languages.

-Note: The only "Common" themes are that 4=A, 6=G, 7=T, 5=S, 3=E and 0=O. The letter F does not exist in most L337. While l= "exists", you'll look like an idiot using it instead of pl-l (or any other letter for H).
