Tongue in cheek

The phrase "tongue in cheek" refers to a manner of speaking or writing where the speaker or writer is being ironic, sarcastic, or making a humorous statement. It implies that the statement shouldn't be taken literally or at face value, but instead is meant to be understood in a lighthearted or joking manner. The term originates from the physical act of pressing one's tongue against the inside of their cheek as a way to signal that they are joking or not being serious.
