can some1 help me???
i want 2 no more bout 13347 or BEAT
it starting 2 annoy me

I think you mean leeat (i thought it was spelled leet). Anyways, its like hacker language. A combination of numbers and letters that spell out a word.

its 1337 - leet - elite speak

just geek speak mainly

Leetspeak is unintelligible in the forums, and I really don't recommend that kind of speak anyway because it takes such a long time to understand the leet sentence or group of words at hand. I know for one that I won't be taking a year to figure out what someone typed in leet.

i no leet but its this thing called beat (13347) ive seen...hmmm...forget it

well ive never heard of it

i think u mean l33t or leet
it is a form of computer lingo that geeks use to prove their awesome geekyness
and yes i can read/speak it to some extent
u might have seen a misspelling or some one tryin got pull it off

Leet, also known as 1337, 7331 and by a variety of other names is a highly complex sort of dialect used primarily in online circles and as Silent Masamune stated, is for the most part completely unintelligible where it is found, partly due to the fact that nobody uses it right. Leet has proved to be the n00b's dialect of choice in many occasions, as that they congregate in droves to exchange it as forms of greeting or disdain. Pay no mind to it. What you are witnessing now is a bastardized clone of 1337 that's been washed through a few successive generations of people who have absolutely no idea of what they're doing, and of course they have destroyed it in hopes of making it easier and more accessible to n00bs everywhere.

p.s. Refer to new people as newbies, and idiots as n00bs. The two are completely different and separate things that should not be confused.
