apart from text speak, are the mispronounciation of words (and please note, all mispronounciations have been deliberately spelled phonetically)
asept (and its relative-aseptible) and if you can tell me what a sept is then more power to you!,
clision (as heard on three news yesterday),
pleece,
appreeseeate (that neighbours favourite),
yoggit,
orf,
preform,
(new edited entry...) harrissment
and the latest i heard on an advertisement (which is possibly why I don’t watch them) gl**ware (i don’t want to slip into product placement here) apparently has a texted surface.
this list is by no means exhaustive. feel free to add your own words.
p.s. sheldon rocks!
