This clip is mainly known as a TikTok reaction sound in Vietnamese-language meme edits and reposts. The phrase “Trời ơi, khoan” spread because it is short, expressive, and easy to understand from tone alone, even for viewers who do not speak Vietnamese. Creators use it as a brake pedal for videos: a quick audio cue that says stop, wait, or do not continue. Its staying power comes from how well it fits reaction memes, abrupt punchlines, and dramatic interruption edits across short-form video platforms.
