I use the momentum of the shockwave and a portal gun to shoot a portal to the moon and use the momentum to fly into a white patch of dirt on the surface of the moon, shooting a portal there. The result sends me rocketing back to earth faster than you were, allowing me to do...THE ULTIMATE CHEST SLAM OF DECIMATION!!! You're sent flying to some unknown continent, while I claim the hill, being left unharmed from all of that.

MY HILL!!!
