Slang used by
hackers and by
gamers on
multiplayer game servers and in chatrooms. 133t
is the slang word for "leet" which is short for
elite, meaning
the best. 133t speak usually consists of
numbers replacing vowels in words (example: A=0, E=3), but occasionally
the numbers will replace a consonant. It cannot really be spoken or handwritten
as such it is considered to be an
Internet language dependent on a
keyboard.
