What is the neckbreaker move?

In professional wrestling a neckbreaker is any throw or slam that focuses its attack on the opponent’s neck.

One type of neckbreaker involves the wrestler slamming an opponent's neck against a part of the wrestler's body, usually the knee, head or shoulder. Many uses of the word "breaker" apply to this sort of action, including: Facebreaker, Backbreaker, etc.

The other type of neckbreaker is a slam technique in which the wrestler throws an opponent to the ground by twisting the opponent’s neck. This also refers to a back head slam where a wrestler drops to the mat while holding an opponent by their neck, without having to twist it.
