First time I saw it was about a year ago in a Dutch music video, then recently I have noticed more and more music videos featuring this dance. After wiki-ing it, I found out it is called JumpStyle. It is mostly related to Europe and techno music and even has different varities as you can read in the wiki link at the end and you can find videos on youtube with that dance.
Nibaq, who is somewhere in the mountains, enjoying the snow messaged me the other day to tell me he saw a new Scooter CD, and at the same time I was watching tv and his new video was playing and it was full of that move, with the song Jumping all Over the World, but I doubt many want to see or hear Scooter, so I will save you from the suffering ;p
Here is the link.
