Whirlwind Spin (旋風回転刃) is a technique used by Oceanus Shenron.
First, the user puts both of their middle and fourth fingers together while the points of the index are placed together, thumbs, and pinkies to create a sign. Then, the user releases his/her hands to form a razor-sharp wind tornado (with him/her as the epicenter) that cuts and damages the opponent, inflicting a great amount of damage.
Oceanus Shenron uses this attack on Goku during her battle with him and Pan. After Goku had countered her spin attack with his own, Oceanus uses the "Whirlwind Spin" on Goku, trapping the Saiyan in a cliff. With Goku helpless, the bird of Colm, a friend of Pan's, dives from above the Whirlwind Spin attack and attacks Oceanus' head. Because of this, Pan figures out the weakness of the Whirlwind Spin: Oceanus is vulnerable to attacks from the very top of her. Pan fires her first perfect Kamehameha at Oceanus, stopping the attack. Free, Goku fires his own, putting an end to the Shadow Dragon.
Later, Omega Shenron uses this attack on Super Saiyan 4 Goku after the latter is frozen by Omega's Super Ice Ray. With subsequent attacks by Mighty Hurricane Fury and Dragon Thunder, Omega knocks the Saiyan to the ground unconscious.
