A. A tough person (either gender, any ethnicity, usually over 22) who can get really pissed off about all the right things (hipsters, gamers without social skills, big government) but doesn't make a big deal about it. Mionas show up at protests, just because it's a good thing to do- they usually protest individually. They do not recognize themselves as a group. Mionas like being good with their hands, and camping, though sometimes they just like the idea of camping and frequently get lost if they do it.
B. A groove/dance rhythm halfway between drum 'n' bass and samba.
Camping with an absent-minded miona would be ridiculously annoying if she wasn't so nice about it.
