This technique was used by Piccolo Dai Mao and a much larger and more destructive variant was used by Freeza. This technique involves waving the arm and having the land explode in it's wake, between you and the enemy. It is usually used as a deterrent rather than a proper offensive assault. It is very similar to the Flame Pillar technique and may even possibly be the same.
