Akanbe (あかんべえ Akanbee), also spelled Akkanbee (あっかんべー, アッカンベー), is a Japanese facial gesture indicating crazy sarcasm, also known in France as mon œil. It consists of someone pulling down one's lower eyelid to expose the red underside towards someone, often accompanied by the person sticking their tongue out. It is considered an immature taunting gesture. The gesture is used often in manga and anime by tsundere characters.
