Poker face is a commonly used idiom which implies a lack of emotions or tells portrayed by the individual. This term comes from the special language used in poker. poker face is not only about your facial expression but also other extraneous movements, This is what sets it apart from similar terms such as having a blank expression

The first recorded publication of the term Poker Face is from the 1875 book "Cavendish. Round games at cards." Which reads “It follows that the possession of a good poker face is an advantage. No one who has any pretensions to good play will betray the value of his hand by gesture, change of countenance, or any other symptom.”
