I don't really know how to explain this video to you. It's one of those pieces of genius that sounds so wrong in theory, yet is so right in practice.
Here's the best I can do: It's a Harry Potter spoof that re-imagines Harry and Voldemort's big climactic battle as that awesome Alex Wong/tWitch hip hop piece from "So You Think You Can Dance" Season 7. And Cat Deeley is played by Ron Weasley. And the dancing is actually totally sick. And Nappytabs have already Tweeted about it. And it is my new favorite thing, ever.
Confused? Get out of your mind (nyuk nyuk) and just watch. You're welcome.
