Place it at the centre of an edit, just before the reveal, then follow it with the Bruh sound for disbelief and the Scream Meme sound if the reaction needs to escalate further.
關於此聲音
This is a short alien meme clip of about eleven seconds, built around a strange, otherworldly effect that sounds deliberately out of place. It gives a listener an uneasy, amused jolt, as if a normal scene has suddenly gone strange. That odd, arresting feeling is why it works as a quick reveal signal, making something familiar feel bizarre for a moment.
