The 'I Don't Know her' meme originates from a 2003 interview where pop superstar Mariah Carey was asked about Jennifer Lopez and responded with the now-legendary three words while shaking her head with a smile. This brief moment of televised shade eventually evolved into a foundational piece of internet culture, representing the peak of dismissive energy. It is used globally to express a refusal to acknowledge someone's existence or to humorously ignore a problem, such as an upcoming deadline or a text message. The meme remains a staple for anyone looking to convey unbothered, high-status indifference.
