L33t is a language used by the users of MarioWiki. To use it, the user must replace all E's in the english with a 3, O's with 0 etc. L33t also has its own words, like "pwn", "RPFL" (commonly misspelled as "ROFL"), and "teh". Mario has used L33t to communicate with the cannibalistic users of MarioWiki. Luckily, he escaped in time. It was also once used by the Foreign Legion.

Grammar

Alphabet/spelling

L33t uses a variation of the Cybernetian alphabet:

@ |3 ( c| € |= C, |-| 1 _i |< 1_ /\\/\\ |\\| |^ ^| |2 $ '][' |_| |/ \\^/ >< '/ 2

L33t differs from other Cybernetian languages, not having an O character. P is used instead. Also, using ph instead of f is recommended.
