A genre of music that is mostly composed of songs from musicals. These songs are played during sex/highly sensual scenes, and carry high intensity and emotion. The most famous fuck ballads are "Dead Girl Walking" from Heathers: The Musical, "Say No to This" from Hamilton, and "Touch Me" from Spring awakening. This genre is fairly small, but well-loved by theatre kids and casual fans alike.
After every last show, I like to lay down, eat pizza, and listen to some hardcore fuck ballads. Really gets me going.
