Er...well you pretend to scissor with someone, pretend to pass them the ball by popping it into the air, but then catch it yourself and carry on running.
if u don't want to look like an idiot by throwing the ball to yourself and actually dropping it, you could try the one giteau does, its the same dummyswitch move but instead of throwing the ball he flings the ball out it one hand behind him, almost to the point of letting it go, then at the last second brings it back in, looks specky i think.
