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!
The group's name says it all - From Legos and lightsabers, to Blythe dolls and board games. (And everything in between, really!)
