The awkward dance that occurs while wearing a Snuggie. This is generally characterized by awkward walking, close to a shuffling motion, in which you are trying not step and fall like a complete idiot. It is also characterized by the occasional stopping to fix said snuggie from falling and making your Snuggie shuffle all the more awkward looking
Rita: Do you see Jack in his new Snuggie? Why is he walking like that?
Janet: Oh that? That's nothing. Jack is just doing the Snuggie Shuffle, because the novelty of wearing a Snuggie hasn't worn off yet.
