Oh! Trash. Waddle Dee obviously knew what that was. Garbage, trash, another man's treasure... that sort of thing. That was such a strange word for it, though. Rubbish? That made it sound like a rubbing motion done differently or something. Dee took things too literally sometimes.

"Oh. I know what trash is, so... that makes sense. I guess these are new human words that I don't know. I think so."
