No, I'm not talking about not some amazing new J-game involving cards and balls (though that actually sounds like it could be awesome). See, there's a Japanese word that has confounded me since I learned it years ago, and that is 「ダンボール」. "Cardboard," in English. Usually when you come across a katakana word drawn from English, you can tell fairly quickly what the base word is or at least guess what it's getting at. Even with 和製英語. With this one, I really had no idea.
