猿さるの尻しり笑わらい

expression, noun

pot calling the kettle black; people in glass houses shouldn't throw stones

Proverbial expression pointing out hypocrisy: criticizing someone for a fault you share. The literal image is a monkey laughing at another monkey's red buttocks, oblivious to its own.

• 彼かれに遅ち刻こくを注ちゅう意いされたが、自じ分ぶんもよく遅おくれるので猿さるの尻しり笑わらいだ。

  He scolded me for being late, but since he's often late himself, it's the pot calling the kettle black.

  Those two laughing at each other's outfits is really a case of the pot calling the kettle black.
