I just discovered that all these years I've been using a stolen catchphrase. On leaving a room inhabited primary by my friends, I often say, "Later taters." I thought that I had just come up with it myself because it just sounded like a funny phrase. Only now have I realized that this whole time I had actually gotten it from Rikku's line in Kingdom Hearts, right before she, Yuna, and Paine leave Sora and co. in the Hollow Bastion castle tunnels. My whole life is a lie.
If you only learned it from Kingdom Hearts, that must mean you didn't meet enough people growing up. I was saying that and hearing it when I was in elementary school
