what is poker face about

"Poker Face" is a song by Lady Gaga from her debut studio album, The Fame, released in 2008. The songs lyrics feature various sexual innuendos and mix sexual and gambling metaphors throughout the lyrics. The main idea behind the song is bisexuality and was a tribute by Gaga to her rock and roll boyfriends. In the lyrics, Gaga sings about being with a man while fantasizing about a woman, hence the man needs to read her "Poker Face" to understand what is going through her mind. The song is about someone hiding their true feelings from others, much as skilled poker players maintain an impassive expression which doesn't reveal their hand. Gaga has also revealed that the song was inspired by her past sexual experiences as well as her bisexuality.
