It depends on where you are. Mostly it's just people in costumes or who really like animal style art hanging out and meeting each other. The parties are loud, the dance is an EDM fueled shakedown where 1000+ people cram into a room and reach critical mass, and most furries love taking over restaurants and tipping well.

There's a lot less sex than the Media likes to show, but "just sorta hanging out with people who share interests and like art" doesn't get the ratings.
