Clips built around a shouted "lets go" followed by nonsense chanting became a staple of meme soundboards and short-form edits because they need no context to read as celebration. The wawawawa part works like a human air horn, turning genuine excitement into a silly, repeatable catchphrase. Short hype shouts like this spread through gaming streams, sports fan edits, and reaction videos, where creators reuse the same audio to instantly signal a win without recording their own voiceover.
