Easily confused with a punch defined as a "bitch move" a true sucker punch is quite a
bit more complex than a simple unanounced attack.
It primarily involves a closed fist contacting the
soft underbelly of a person (beneath the rib cage) at a
high velocity, causing the ensuing force to press upward on the victim's diaphram, leading to a sudden expulsion of
air from the victim's mouth and lungs. This opening
blow leaves the victim open to various other attacks, often leading to what would be called "bitch moves" becuase of the defenseless nature of the victim.
