Daithi De Nogla, an Irish YouTuber, became known through his long-running collaborations with VanossGaming, where his loud, excitable reactions became a running feature of their multiplayer videos. The repeated let's go chant comes from that high-energy gaming style, rather than a single scripted scene, and fans clipped it because it summed up his personality in a few seconds. It has since circulated as a short reaction sound for gaming edits, Discord jokes and TikTok-style clips, where it works as instant hype before a match or challenge begins.
