JoJo Siwa released Karma in 2024 as the lead single of her adult pop reinvention, moving away from the child-star image that made her famous on Dance Moms and YouTube. The song's blunt hook quickly travelled on TikTok, where users paired it with revenge stories, failed schemes and moments of poetic justice. Its short, quotable line made it easy to lift into edits, reaction videos and memes, and it remains in use because the idea of karma striking back fits almost any comeback, betrayal or comeuppance clip.
