The term 'Comic Book Punch Sound' refers to two sound effects commonly used in comic books. The first is 'POW', which is a three-letter sound effect that is usually used to indicate a punch or a hit. The second is 'KAPOW', which is a five-letter sound effect that is usually used to indicate a more powerful punch or hit. These sound effects are often used to emphasize the action in comic books and add to the excitement of the story.
