The Moai, or Easter Island heads, are famous stone monuments, and their impassive faces became a visual shorthand online for a deadpan, unbothered reaction, especially in short-form video and meme edits. Rather than coming from one film or song, this sound effect circulates as part of that wider Moai meme language, where creators attach a heavy, ancient-sounding cue to an otherwise ordinary moment. Its staying power comes from that simple contrast: the statue never reacts, so the sound does the reacting for it, turning silence into a punchline.
