pot calling the kettle black

The phrase "pot calling the kettle black" is an idiom used to point out the hypocrisy or inconsistency of someone who accuses or criticizes another person for a flaw or behavior that they themselves possess. It implies that the person is being unfair or judgmental while ignoring their own similar faults. The phrase originated from the practice of cooking or boiling on a stove, where both pots and kettles would become blackened with soot or dirt, making them indistinguishable in color.
