ASCIIbonics

    (From ASCII and Ebonics) A style of text
   communication in English which is most common on talk
   systems such as irc.  Its notable characteristics are:

   Typing all in lowercase (and occasionally all in uppercase).

   Copious use of abbreviations of the sort "u" for "you" "1" for
   "one" (and therefore "some1" for "someone", "ne1" for
   "anyone"), "2" for "to", "r" for "are", etc.

   A general lack of punctuation, except for strings of question
   marks and exclamation marks.

   Common use of the idiom "m or f?", meant to elicit a statement
   of the listener's gender.

   Typical extended discourse in ASCIIbonics: "hey wasup ne1 want
   2 cyber?"  "m or f?"

   ASCIIbonics is similar to the way B1FF talked, although B1FF
   used more punctuation (lots more), and used all uppercase,
   rather than all lowercase.  What's more, B1FF was only
   interested in warez, and so never asked "m or f?".

   It has been widely observed that some of the purest examples
   of ASCIIbonics come from non-native speakers of English.

   The phenomenon of ASCIIbonics predates by several years the
   use of the word "ASCIIbonics", as the word could only have
   been coined in or after late 1996, when "Ebonics" was first
   used in the US media to denote the US English dialects known
   in the linguistic literature as "Black Vernacular English".
