German friend teaches me to levitate

In some kind of game world (basically a suburban/semi-urban setting with parks and stuff), my German friend (not a real person) is demonstrating how to levitate. I'm watching what he does. He starts out by crossing his legs slightly (while standing up, mind you), and then some other fancy stuff and voilà. It takes me a minute, but I finally seem to have it figured out. I cross my legs a little, then spam the space bar, while continuing to move around with the direction keys. I go back to my home base and show my friend there.
