dork

Dork is a slang word for a quirky, silly and/or stupid, socially inept person, or one who is out of touch with contemporary trends. Popular etymology would have it that this slang term comes from a term meaning a whale's penis. That is half right.

The term did originally mean a penis, but human not cetacean. This slang sense dates to at least 1961 and is probably a variant on dick or "dirk" (another name sometimes used to personalize the phallus). The sense meaning a stupid or obnoxious person follows a few years later, 1967.
