What Does “Poker Face” Mean?

Example Dialogue
- Alice: Did you see Tom's reaction when they joked about his mistake?
- Ben: No, he kept a poker face the whole time. Couldn't tell if he was angry or laughing.
Note: This phrase is informal and casual. Saying “poker face” in a formal meeting might sound odd unless everyone knows what you mean.

What Does “Straight Face” Mean?
Literal Meaning: “Keeping a straight face” means not smiling or laughing at something funny or inappropriate, maintaining a serious expression.
Figurative Meaning: It’s about not showing amusement or emotion, often when trying to be polite, professional, or to hold back a reaction when it's englishrulebook.com not suitable to laugh or smile.
Example Dialogue
- Carla: I tried telling a joke during the meeting.
- Dave: And did anyone laugh?
- Carla: Nope, but I kept a straight face so it didn’t feel awkward.
Note: Keeping a straight face works in both casual and formal settings. It’s useful in professional meetings, like those noted by VOA Learning English for workplace communication.
