Offering some words about her new single on socials, Halsey wrote, "imagine getting onstage every night and seeing young women sweating mascara tears, lightning in their eyes, throwing elbows and raising fists, screaming till the veins in their necks raise under warm skin, and not being inspired by it. This song is about you, for you."
