While it’s obvious on even the first listen that Lady Gaga’s “Poker Face” is filled with sexual innuendo, it’s initially not quite as clear that the song describes a specific sexual experience Lady Gaga had.

According to the singer, the song’s lyrics detail a time she fantasized about a woman while being intimate with a man, the “poker face” in question being her expression to not allow her male lover to realize what she was really thinking about.
