Someone who sits alone in a corner and hardly speaks to anyone. You often find these sad people, very similar to emos, at parties or alone in a corner at the office.

A really uncool person that was accedently invited to a party. A corner dweller is usually found in a dark corner of the host's house drinking a juice box.
