The Twin Rasengan technique is simply the simultaneous use of two Rasengan by the user, with one in each hand.
Trivia
- When Naruto performed this technique in the movie, he used two different versions of the Rasengan, the Gelel Rasengan, with the aid of Temujin (who helped form it like a shadow clone would normally), and the Demon Fox Rasengan, with the aid of his shadow clone.
- Jiraiya does something similar when teaching Naruto how to use the Rasengan; in one hand he forms a regular Rasengan, and in the other he does the balloon exercise.
