Norfolk Enchants (or the meaningless 'Norfolk in chance'???), Universally Challenged and Quizlings are ones that were once funny, but they've been so overused, they just sound so completely unimaginative now - especially when the team announce their name with a loud 'aren't we hilarious' chuckle.... even more so when you get another team called the same. However funny something is at first, as soon as it gets copied and spread, it loses all humour very quickly.
I went to a quiz some time ago where there were two teams with effectively the same weak-pun name - one letter different, but no difference normally in pronunciation. The quizmaster ended up having to unnaturally emphasise the one letter difference, in order to distinguish between the two. What was probably intended to sound quite clever just ended up so cringeworthy.
Almost worse are the ones where nobody has made the slightest effort - even when they've known for weeks that they're doing the quiz and need a good name. I've been to so many quizzes where there are teams called 'Us In The Corner', 'Him & Him & Her', 'The Two of Us' and similar.
I like the topical ones and those that are designed to tease/confuse the quizmaster; but beware of ones that are too long, as the QM will just end up abbreviating them. I once went to a quiz where there was a (surprisingly mixed) team called 'My Girlfriend Is No Fighter But You Should See Her Box'. Hilarious, I'm sure if you're 13 - but they were just referred to as the mundane 'My Girlfriend', which didn't really have the desired effect.
I think you have to come up with something yourself, ideally avoiding any riff on the word 'quiz' as, funny though they originally were, they're just all so old and overused now. Maybe use a slightly-bowdlerised MN phrase that will leave everybody else scratching their heads in puzzlement but will instantly identify any fellow MNers in attendance. Something like 'The Rank Badgers' or 'The Sock Wombles'
