“Funnily enough ‘mallgoth’ was meant to be a bit of an insult,” explains Trinity Levy, the Arizona-based high school senior who started the Instagram account @1990smallgoth. “Being called a mallgoth was the equivalent of being called a poser. The purpose of it was to describe the kids who loved Marilyn Manson and bought Tripp pants from Hot Topic back in the day, but still identified or were seen as goth. I'd say that that broad description is still true at its core. Despite its name, it doesn’t have anything at all to do with the goth subculture besides sharing a few aesthetics.”
