Cosplay (コスプレ, kosupure), short for "costume play". It ain't a hobby, it's a lifestyle!
Movies, books, TV, comics, games, hobbies, interests, obsessions, anything and everything that affects your life and isn't covered in the other groups!
Silliness, randomness, drunkenness, attention-whoring, entire threads devoted to pictures of kittens. It's all in here. For when you have nothing to say but just can't stop posting.
