The phrase is Thai and is commonly transliterated from the raw title 03 luuk iikhn, which is why searches use several different spellings. No clear original source work, speaker or year is documented for this upload, so its life is mainly online as a shared soundboard clip. At under a second long, it spread in the way very short reaction sounds do, through replays, edits and chats where timing matters more than context. It remains used because the delivery is instantly recognisable and easy to place over almost any sudden, extra or unwanted appearance.
