Lady GaGa told Fashionista101 that this tune is about the singer playing with guys as if she was a poker player. She explained: "The song speaks in reference to the poker game, 'Texas Hold Em.' So I said, 'I wanna hold him like they do in Texas, please.' So its basically saying like, I wanna hold that guy — I wanna be close to him."

The "Mum-mum-mum-ma" hook is sampled from Boney M's 1977 hit "Ma Baker."

"Poker Face" is an electropop song by American pop singer-songwriter Lady Gaga from her debut album, The Fame. Produced by RedOne, it was released as the album's second single in late 2008 for some markets and in early 2009, for the rest of the world. The song is an uptempo dance song following the foot-steps of her previous single "Just Dance" but has a darker musical tone. The main idea behind the song is bisexuality and was a tribute by Gaga to her rock n' roll boyfriends. The song contains words like muffin which Gaga used as a metaphor for vagina. Lyrically "Poker Face" is about sex and gambling.

"Poker Face" has been well-received by the critics with most of them appreciating the robotic hook and the chorus. The song has attained worldwide success, topping the charts in more than seventeen countries including the United States, United Kingdom, Australia, New Zealand, Canada and many European countries. The accompanying music video for the song portrays Gaga singing it in various costumes and playing strip poker in a mansion.

The song has been performed on a number of live appearances by Gaga including the eighth season of American Idol and her first headlining Fame Ball tour where alternate variations of the track have been performed, including a piano version which she played while wearing a dress made of bubbles, and an electronic version.
