Fallout is a long-running post-apocalyptic role-playing game series built around exploration, quests and character progression, with experience points driving levelling up. The short XP chime has become a familiar audio cue for players, because it accompanies that moment of progress after finishing an objective. As gameplay clips and memes spread on video platforms, editors began reusing the sound outside the game to mark achievements, jokes and personal milestones, which is why it still appears in gaming edits and short-form videos today.
