This short Mandarin phrase, meaning 'I've been discovered,' has become a useful reaction sound online because its meaning is clear even to listeners who do not speak Chinese. Creators use it in short videos, game clips and memes to mark the exact moment someone is caught, found hiding or exposed in a joke. Its brevity makes it easy to drop into fast edits, and its panicked tone gives an instant comic payoff without needing subtitles or extra context.
