I have coined the phrases (1) "A giggle of girls," (2) "A banter of boys," and (3) "A choir of humming birds."
Robert, you might want to check those against Googlemark. http://www.googlemark.org/
One of my favorites is "An indifference of Waiters" also "A Fanfare of Strumpets"
I used to hear that the collective nouns applied to animals—a murder of crows, a crash of rhinocerota, an exultation of larks—were official but forgotten, that "a herd of whales" or "a flock of minnows" is simply wrong. But conversations like this strengthen my suspicion that back when they coined "a shrewdness of apes" they were just having fun, as we are now.

I recently was forced to abandon a shop that was infested with "a coven of Brittneys".
