@Perikles: I know they're difficult. My favourites so far were a congress of baboons (no wonder) and a murder of crows. I wonder who on earth has named flocks of specific species with a different name for each. In Spanish they're far less varied.
Thanks for the link.
@Sancho: Of course, this is not a word to be found in my daily conversations, so I hadn't ever heard it, even from my British friends. Anyway, I'm always happy to learn new words, and I can't wait to use it soon even if I have to introduce a weird chat topic.
