We'll be the first to admit that we're not up on the latest trends, so every now and then, we need an explanation of what the hell is going on in the world.  Now we've heard of Hentai before, but weren't exactly positive of the definition.  We knew it had something to do with Japanese animation, but that was about it.  Good thing a video popped up of this guy attending last year's Dragoncon convention, who gave us a complete explanation of exactly what Hentai was.
