The pot calling the kettle black

Proverbial idiom referring to an example of hypocrisy

"The pot calling the kettle black" is a proverbial idiom that may be of Spanish origin, of which English versions began to appear in the first half of the 17th century. It means a situation in which somebody accuses someone else of a fault which the accuser shares, and therefore is an example of psychological projection, or hypocrisy. Use of the expression to discredit or deflect a claim of wrongdoing by attacking the originator of the claim for their own similar behaviour is the tu quoque logical fallacy.
