1950s slang for nerd. A "policy wonk", for example, is someone who loves policy to a truly geeky degree.

A weird person. A term used by MegaZeuxers, probably derived from the Australian slang word wonky. Can also be used as an interjection in response to a bizarre occurrence: "Wonk!"

Wonk was the name of a koalabear in an old series of children's books.

Because of the overwhelming resemblence and his portly physique, Norman Lamont (an ill-fated and rather hapless Tory Chancellor of the Exchequer) was often referred to as Wonk. It is highly unlikely, however, that Wonk-the-koala would ever have consorted with Miss Whiplash or bounced cheques at his local offlicence.
