Bananas come in bunches, wolves in packs, locusts in swarms, but what do you call a collection of Unitarian Universalists?
Some obvious collective nouns are too easy and not specific enough: A congregation of UUs fits, but it would also fit just about any other religious group. Also, it's too formal and is so wedded to whole churches that it would be confusing to apply to smaller collections. When you take the youth group out on a hike, congregation doesn't really work.
Christian use that Good Shepherd imagery and so flock works for many of their groupings, but UUs hate to be compared to sheep. If we sang better, a choir of UUs might work, but angels come in choirs, and besides there's the whole reading-ahead-to-see-if-we-agree thing.
A committee of UUs is sadly apt, but I hope we can do better, something more along the lines of an exaltation of larks, a parliament of rooks, a murder of crows, and so forth.
So what are we? A curiosity of UUs? A cacophony? A cafe?
An evolution of UUs? (I kind of like that one.)
