An insult, usually used after losing an online argument, by lunkheads (see alpha male) towards those with superior knowledge or intellect, as a way of trying to change the subject and thus become the victor or to save
face after proving themself to be less intelligent online than someone else. In the days before the
internet, after losing a verbal argument, a
person using this term today would physically attack the winner of a verbal battle, attempting to become the victor of a physical battle. In business, commonly used by those in management to refer to less vocal and therefore
non-management staff (see promotion has nothing to do with ability). Usually the target of the insult is disabled in some way, e.g.
autistic or mute, therefore the term is a form of discrimination or bullying.
"That non-verbal autistic guy thinks he's so
smart but he's just a keyboard warrior, he wouldn't dare say that to my
face or I'd smash his
face in."
