I guess it depends on context i.e. I think that were you to find a knot of snakes in your bed and neither you nor a loved one put them there then "shitstorm" would probably be the preferred nomenclature.)
OK, I know this is a long-dead thread, but I've just stumbled upon it and can't resist. So for anyone who still cares, regarding the definitive term, I turn your attention to one of my most favouritest of bands, the indomitable Wire, and their song: A Serious of Snakes (http://www.amazon.com/A-Serious-Of-Snakes/dp/B000XN25PM). 'Nuff said.
This has long been my go-to for collective nouns. It suggests bed, knot, nest, pit, or trogle (?), but rattlesnakes get their own: rhumba.
I'm proud to have found so far no Google results for a suggestion of my own, a goiter of jabiru.
I'm itching to read Lipton's book. A score of bachelors, huh? But I love this site best because of the People category (a neverthriving of jugglers!), and especially because of something in the Some That Might Be category: a fraid of ghosts.
