Overgeneralization
Jargon Construction
Anthropomorphization
Spoken inarticulations
Words such as `mumble', `sigh', and `groan' are spoken in places where
their referent might more naturally be used. It has been suggested
that this usage derives from the impossibility of representing such
noises on a comm link or in electronic mail, MUDs, and IRC channels
(interestingly, the same sorts of constructions have been showing up
with increasing frequency in comic strips). Another expression
sometimes heard is "Complain!", meaning "I have a
complaint!"
