wiktionary has an appendix which is a searchable database of collective nouns, those nouns used to collect a group of other nouns, like a "pride" of lions, or, famously, a "murder" of crows. You can search by collective noun, or noun, and they include both standard and ... uh ... made up ones.
This is another item--the quirkiness of collective nouns--that has become popular and trendy lately. I've seen lists of collective nouns in recent quirkster books and mentioned in various quirkster contexts. I'd hesitate to align myself with the forces of collective quirk ... only, it's a database!
I like a "hand" of bananas and a "stare" or a "parliament" of owls (both are so appropriate, no?)
