wikipedia - 18 Jul 2021A rabbit punch is a blow to the back of the head or to the base of the skull.[1] It is considered especially dangerous because it can damage the cervical vertebrae and subsequently the spinal cord, which may lead to serious and irreparable spinal cord injury. A rabbit punch can also detach the victim's brain from the brain stem,[2] which can kill instantly.
