Cover art for Turned Blue lyrics by Caroline's Spine

This song is about Erotic asphyxiation also known as asphyxiophilia, breath control play, or scarfing. This is the practice of intentionally reducing the amount of oxygen to the brain during sexual stimulation in order to heighten the received pleasure from orgasm. The girl was telling him to do it to her and he only wanted to please her but ended up killing her.
