Pinballing is the name that is given when a projectile, such as Mario's Fireball, is constantly being reflected by an attack that can reflect such a projectile. A notable example is King Dedede's Gordo Toss. The Gordo in SSBU can be reflected by any attack, back to King Dedede, who simply Inhales it and spits it out, back to the opponent, who easily reflects it again. Pinballing is not indefinite. Regardless of the speed of the reflector, reflectors can actually fail if they take enough hits within a certain time, almost always resulting in a KO. It is possible for a character to do something called a Halfball, which is when the character launches a slow projectile, and more or less reflects it. The projectile will not change direction, but it does deal more damage and also go faster.
