I think you are right. As RC would have said "super pumped." In all seriousness... that is awesome to watch a kid that excited to race/ride. Awww... to be young again.
I don't even have to watch the video to know which one it is I posted this up on facebook a couple months ago, I think that it's hilarious. Little guy is TOO pumped, more kids need to be enthusiastic like him when it comes to riding.
