From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia
The Saturday Crush (サタデー クラッシュ, Satadē Kurasshu) is an energy sphere used by Raditz. First, Raditz holds his right hand high in the air and forms a pink energy sphere. Then, he fires off the sphere at the opponent, inflicting a great amount of damage.
Raditz used this attack in his battle against Son Goku and Piccolo. While Piccolo charged his Special Beam Cannon, Goku fired a Super Kamehameha down at Raditz. Raditz, however, neutralized the blast with his own Ki and then fired the Saturday Crush up at Goku, striking him down to the ground.
