:hakspek: /hak'speek/ n. A shorthand method of spelling found on
many British academic bulletin boards and {talker system}s.
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 talker systems, which
operated on archaic machines with outdated operating systems and
no standard methods of communication. Has become rarer since.
