The deflect sound comes from Star Wars, where Jedi and other lightsaber wielders block incoming blaster fire with a glowing energy blade, turning defence into an instantly recognisable moment of skill. As the films, animated series and games kept returning to that image, the short clash became shorthand for a perfect block in fan edits, parodies and gaming videos. It remains popular because it needs no context: one zap tells the audience a shot was stopped, a fight is turning, and the hero is in control.
