The lyrics in "Fake Happy" discuss, as the title suggests, putting on a brave face despite struggling internally. "I hate phoniness," lead singer Hayley Williams said in an interview with Beats 1. "It's not fun to be around, it's not fun to do yourself. But then there are these moments in your life where you're professional and you have to have grace with yourself, you have to have grace with other people and work hard, but it's that self-preservation thing."
