Group names

I've been messing about with the dictionary widget on igoogle and came across some rather funny words. What exactly is a clowder of cats? I know it's a group, but where do these words come from? And what would you call a group of nerds?


Hmm... Now I'm thinking. This is a dangerous thing. Okay, how about "a niggle of nerds"? "A program of geeks"?  "A forum of gamers"?


Can anybody think of a better term?
