What do you mean by poker face and who has sung that song?
Responses (3)
A "poker face" is a face that shows no emotion just like a poker player who doesn't want to give away whether he has a good hand or not through his/her facial expressions. The song "Poker Face" was a chart success for the pop star 'Lady Gaga' (who wrote it and produced it I don't know, you could easily find out by googling it).
