Fallout: New Vegas is a 2010 role-playing game set around a post-apocalyptic Las Vegas, where casinos on the Strip feature playable slot machines. The spin sound comes from that gambling minigame, separating the pull and reel movement from the ambient casino noise. Clips of the effect later circulated on soundboards and in gameplay edits, detached from a full casino session. It remains popular because the short spin instantly signals chance, risk and a possible jackpot without needing any visual context or explanation for viewers familiar with the game.
