The phrase let's go has long been a staple of sports crowds, gaming streams and reaction videos, where the stretched spelling with extra o's became a visual shorthand for maximum excitement online. Short audio versions spread through meme soundboards and short-form video edits, where creators reuse the same hype shout to punctuate wins without needing any context. Like a long celebration yay, it works because everyone recognises the feeling instantly, which is why it keeps appearing in new edits years after the original shout first circulated.
