Tu quoque is a Latin phrase, which means "you also" or "you too." It's often a retort to an accusation or criticism, where the speaker points out that their accuser has also done the same thing. However, there are several other words and phrases that can convey the same idea, such as reciprocal accusation, mirror accusation or reverse accusation. Another synonym for tu quoque is the term "whataboutism," which has been used in recent years to describe a tactic used in political discussions or debates where an individual deflects criticism by pointing out similar actions taken by their opponents. These synonyms can be used interchangeably to describe the act of countering an attack or criticism by pointing out the same behavior in someone else.
