Name calling requires swiftness, want to get higher, to last longer than the opponent, and of course some kind of strength usually.
The name calling trainer is a ball that is launched by shouting into a bullhorn. The bullhorn is actually a scoop for throwing the ball, but that's part of learning
how to use it.
The ball is attached to the thrower by a tether. This teaches the name callers to always move forward when they call a name, especially when it is a team sport. The ball also rebounds on an elastic cord to show how name callers should always be punched in the face, but sometimes get away with it.
