An internet sub-language used to either disguise what is being said, so that those who don't know it can't understand (especially authority), or as internet/gaming shorthand.

Commonly humourous and antagonistic
e.g. d00d i p(-)|_|9|<1|\|6 pwn

A basic shorthand form has now infected mobile phone texting and wannabe teenage speak, but that is weak and annoying - typified by people who can't actually spell rather than a clever disguise.

Written well it is as attractive and versatile as any language, and can be written in different ways.

Naturally, people who don't 'get' computers or gaming do what they always do to things they don't understand - they attempt to ridicule (handlover? Shanjay, WTF?), serving only to make themselves look all the more ignorant...
