The sound comes from Shoop Da Whoop, a mid-2000s internet meme built around a face with huge lips charging a laser from its mouth. The phrase and delivery were popularised by The Lazer Collection, a series of short YouTube animations where characters fired beams at each other for no reason. Its intentionally bad drawing and booming audio made it easy to remix into other shows, games and reaction videos. It remains a shorthand for an exaggerated energy attack, instantly understood by anyone who grew up with early meme culture.
