hakspek
     
         /hak'speek/ A shorthand method of spelling found on
        many British academic bulletin boards and {chat} systems.
        Syllables and whole words in a sentence are replaced by single
        {ASCII} characters the names of which are phonetically similar
        or equivalent, while multiple letters are usually dropped.
        Hence, "for" becomes "4"; "two", "too", and "to" become "2";
        "ck" becomes "k".  "Before I see you tomorrow" becomes "b4 i c
        u 2moro".  First appeared in London about 1986, and was
        probably caused by the slowness of available {talk} systems,
        which operated on archaic machines with outdated {operating
        systems} and no standard methods of communication.  Has become
        rarer since.
     
        See also {chat}, {B1FF}, {ASCIIbonics}.
