What it means
Brat summer is an unapologetically bold aesthetic and mindset that surfaced as a summer-long meme on TikTok in 2023. It fuses the hyper-energetic, rebellious vibe of Charli XCX’s album *brat* with a deliberately “messy” visual language: smudged eyeliner or lipstick, ripped tees, glittery or sheer bras, neon or oversized sunglasses, and a palette that leans heavily on Y2K neon, pastel-candy, and Bratz-inspired glossy lips and exaggerated lashes.
The look is meant to look half-finished, as if the wearer has just rolled out of a party, a club, or a late-night cigarette break, and it often includes accessories that scream “trash-y but confident” (e.g., chain-link belts, chunky platform shoes, or a cheap-looking tote).
Beyond clothing, brat summer signals a lifestyle attitude: a carefree, self-affirming rebellion that says “I’ll do whatever feels fun, even if it looks a little uncouth.” Users invoke the term to describe a single outfit, a day’s mood, or an entire summer philosophy centered on confidence, playful defiance, and a tongue-in-cheek embrace of the “cunty” energy described in the original Urban Dictionary entry.
A fringe, unrelated definition equates the phrase with “rodent infestation,” but that usage is isolated and not part of the mainstream cultural conversation. [1][2][3]
Where it came from
First seen: TikTok, 2023
The phrase originated on TikTok during the summer of 2023 as a fashion-lifestyle meme that directly references Charli XCX’s album *brat*. The album’s artwork, promotional videos, and sonic aggression presented a visual lexicon of neon, glitchy graphics, and a brash, youthful swagger.
Early creators paired the album’s aesthetic with the seasonal desire for a “hot girl summer” vibe, posting outfit “dumps,” makeup tutorials, and day-in-the-life clips under the hashtag #bratsummer.
The meme’s language draws heavily from two earlier cultural touchstones: the early-2000s Y2K revival (think low-rise jeans, butterfly clips, and holographic textures) and the Bratz doll aesthetic, which is characterized by bold makeup, exaggerated eyebrows, and a glossy, doll-like finish. By remixing these nostalgic cues with Charli XCX’s modern, rebellious sound, users created a hybrid that felt both retro and freshly transgressive.
The trend quickly spread across TikTok’s algorithmic feed, with creators from fashion influencers to college students adopting the tag, and it was subsequently catalogued on slang-tracking sites like SlangDecoded and Slang.net, cementing its place in the digital lexicon. [1][2][3]
Why it's everywhere
Brat summer rides the rapid-cycle meme economy of TikTok, where a new album release can instantly become a visual template for an entire season. Charli XCX’s *brat* provided a ready-made soundtrack and a set of striking graphics that creators could overlay onto their summer content, making the trend easy to replicate and remix.
The aesthetic also taps into Gen Z’s love for bricolage: it stitches together the nostalgic pull of Y2K fashion, the iconic Bratz doll look, and the established “hot girl summer” narrative, but adds a deliberately unpolished, “trash-y” edge that feels more authentic than the highly curated influencer feeds.
Each summer, the hashtag resurfaces as users look for fresh ways to signal confidence and rebellion, and brands have begun to co-opt the vibe for limited-edition drops (e.g., neon sunglasses, glittery bra tops), further amplifying visibility. The combination of a high-energy soundtrack, a clear visual cue set, and the cultural appetite for remixing past aesthetics ensures that brat summer remains a recurring, searchable trend rather than a fleeting flash.
