If anyone of you had seened the playdia special, you would know what a Super Kamehameha is. In the playdia special everyone is standing around charging up there best attack (besides piccolo he is out), while hatchinsack is charging his move also, Goku is counting and has his Kamehameha charged up and everyone else does, Then at the last second Goku makes his kamehameha grow bigger then it was and say, CHou meaning super or ultimate (i cant remember which) KAMEHAMEHA!. Thats a super kamehameha folks.
