Just got this in an email, and I felt it was worth resurrecting this thread:

"Asylum seeker, economic migrant, bed-blocking, and stakeholder pension reflect the serious side of life; bunny-hugger (a conservationist or animal lover), chick flick (a film appealing to women), gearhead (a car enthusiast), and Grinch (a spoilsport or killjoy) are entries in a more light-hearted vein. Several entries are testaments to the popularity of science fiction, among them Tardis from the TV series Doctor Who, Jedi from Star Wars, and Klingon from Star Trek."

I have no idea what the source is... I'll see if I can't find out.
