poker-faced
PRONUNCIATION: (PO-kuhr fayst)

MEANING: adjective: Having an expressionless face, giving no hints of one's thoughts and feelings.

ETYMOLOGY:
From the necessity of not showing emotions in a game of poker to avoid giving other players an indication of the strength of one's hand. The origin of the term poker is uncertain. It may be from French poque (a similar card game that involves bluffing), from German pochen (to knock, brag). Earliest documented use: 1915 (for the word poker: 1832).]
