@Neo: I think the video itself is supposed to be about some of the many JP memes (mostly dances) that are on Youtube or that Nico Nico something whatever its called. I recognize that "dance" at 1:11 for example.

Many other anime/manga characters have been used for this video just like Luffy, Kid and Law.
