입만 열면 거짓말이 자동으로 나와

A short Korean voice clip where the speaker says lies come out automatically every time they open their mouth, used as a sarcastic reaction to dishonest claims.

This is a brief Korean spoken line delivered in a deadpan, matter-of-fact tone, lasting under three seconds and built around a single self-deprecating confession: whenever the speaker opens their mouth, lies simply come out on their own. The flat delivery makes the exaggeration land harder, turning an admission of dishonesty into something funny rather than serious. It works because it sounds like a casual shrug rather than a dramatic reveal, so viewers instantly recognise it as a joke about someone who cannot be trusted to tell the truth. Dropped over a reaction shot or a failed excuse, it gives the moment a sharp, knowing punchline without needing any explanation.
