Waggle.

I might just have the wrong idea of what 'waggle' is, but I was always under the impression that people used 'waggle' to refer to games on the Wii where a quick shake of the controller acts like a button. Like in Metal Slug, how you'd shake the controller to throw grenades. Or Zelda, where you shake the controller to swing your sword. You're waggling the controller, so there you go! It's waggle. But a lot of times people seem to use it to describe motion sensing in gaming completely, like with the PS3's 'Move'.
