The new Charli XCX album, "Brat," has sparked a cultural phenomenon among fans, who are embracing a new sense of self-identity. A brat is defined as someone with a bold, self-centered attitude, challenging norms and behaving cheekily. Fans like Biz Sherbert see Charli's persona as a source of inspiration, reflecting a desire for assertiveness and bravado. In Washington, D.C., longtime fan Kelly Chapman describes a "brat" summer as one where women in their 30s reject expectations, have fun, make bold moves, and even date someone from Twitter. The album's release has prompted fans to embrace their wild side, with sheer white tank tops, skinny cigarettes, and questionable 3 a.m. decisions becoming symbols of this newfound attitude. As fans find a connection with the term "brat," they are redefining what it means to be confident, rebellious, and unapologetically themselves.
