Pokerfaced is a word that is used to describe someone who maintains a calm and emotionless expression even when they are feeling strong emotions on the inside. There are several synonyms for this term, including stoic, expressionless, impassive, unemotional, unresponsive, and immobile. A person who maintains a pokerfaced expression can come across as mysterious or difficult to read, making them seem unapproachable or even intimidating. However, it can also be an effective way to maintain control in tense or emotional situations. Regardless of whether one chooses to be pokerfaced or not, it is important to be mindful of the way one's expression may be perceived by others and to use it appropriately.
