Gotenks produces the attack by blowing out what appears to be a golden-colored balloon that soon bursts in a blinding flash of light into a cluster of Kamikaze Ghosts. Overall, it is just an easier way of unleashing the Super Ghost attack without having to take such a deep breath.
Gotenks uses this attack during his battle against Super Buu, who gets himself blown inside out by the increased strength of the ghosts.
Another follow up to the Super Ghost attack can be the Super Ghost Kamikaze Attack x 100, which Gotenks uses in the movie Dragon Ball Z: Fusion Reborn. This is much like the regular Super Ghost attack, except they are released at a very quick rate.
