The 'Not In My World. Not In The World I'm Living In' meme stems from a viral video clip where an individual expresses a vehement rejection of a specific idea or social norm, asserting that such things simply do not exist within their personal reality. It has become a go-to template for internet users to mock absurd trends, unrealistic expectations, or to jokingly flex their own high standards. Often used on platforms like TikTok and Twitter, the phrase serves as a humorous 'reality check' or a way to signal that the creator operates on a completely different level than the subject of their critique. Its popularity lies in its versatility, fitting perfectly for everything from dating preferences to workplace grievances.
