arguably not even an English sentence.

ADBOC. Well, if you have something against textspeak (or txtspk, compare newspeak) how about acronyms, such as 'laser'? The analogy seems to hold: as long as you agree beforehand on their meaning - as, indeed, must be done with all words - the brevity would be a virtue. Though, I suppose, YMMV.

It's also arguably an aesthetic affront (as is the at first accidental alliteration).

Agree with the first, strongly disagree with the second.
