What does pockerface mean?

"Pokerface" refers to an expression that reveals little or no emotion, often used to conceal one's thoughts or intentions, especially in a high-stakes situation like a Poker game. The term suggests a calm and inscrutable demeanor that prevents others from reading one's feelings or reactions. It has also been popularized in popular culture, notably by Lady Gaga's song "Poker Face," which explores themes of love and deception.
