I understood this question differently. Rather than the OP wondering the background behind the name, I thought he was asking why had Kishimoto decided to call this what he decided to call it rather than Multipurpose Magical Black Balls of Wonder or whatever. Anyway, there was no need to restore this, considering the answer was given.
