Originating in the early 1980's, leet speak was first used by hackers as a way to prevent their websites/newsgroups from being found by simple keyword searches.
Leet speak grew and became popular in online games such as Doom in the early 1990's as a way of suggesting that you were a hacker (h4x0r), and therefore to be feared.
Leet, or 1337, is a short form of "elite," commonly used by video gamers to suggest that they are skilled.
Leet: l337
Hacker: h4x0r
skills: s|<1llz
Own: Pwn

A form of writing whereby some letters in a word are replaced by a numerical likeness or other letters that create an identical or similar sound.

This style of writing was originally in use by hackers who were attempting to bypass word-filtering on mail servers. For instance, they would use the term 'haxorz' to replace 'hackers'. Internet users new to hacking adopted the style in an attempt to emulate those more experienced, and usage became widely spread.

In recent times the method is almost never used to avoid word-filtering software, but rather to satirise script kiddies and 12 year olds, or to abbreviate for faster typing. It's interesting to note that in most cases it takes more time to type in leetspeak (due to the constant swapping between numbers and letters) than it would take to just type the words properly.

When using leetspeak, you should be aware that you are almost definitely coming across as a moron.

Here, Person A appears to be of below average intellect, due to his/her liberal use of leetspeak.

When the 1st l33t sp34k hit the scene in the very early 80's it didn't use all the annoying ?|}{)\ and crap they put as subs for letters today. It just occasionally subbed some numbers for letters so that normal searches and bots, ect. would not pick up the pattern. It has been changed into something entirely stupid and unreadable by wannabe, lazy kids today. Same with lol and rotflmao and such. Been around since 300 baud n00bs.....
If j00 w3r3 r34lly l33t j00d kn0w it n00b.

This sentence would have been a bit overkill even then for leet speak. Most would have written it like:

If you w4s l33t u'd kn0w noob.....
