When a person playing basketball shoots up to the rim in a complete pencil like shape with the ball in two hands above their head with their arms fully extended. The person does not change position in mid air until the dunk is completed and both feet have landed on the ground. The Human Torpedo can be used to achieve a "Master Eng" which is a different term.
"He just did a human torpedo!"
