Promortalism, also known as hyphenated form pro-mortalism, is a philosophical position for any sentient being, it is always the best to die as soon as possible.
An eating disorder that can occur up to a year, but usually a month before Prom. Mainly occuring in young women, characterized by a self-induced starvation in order to fit into their Prom dresses or feel better about buying a slightly smaller size (which never works). Exercise in the form of "Prom night sex" usually follows Promorexia.
