The 'Santa Deniers' meme is a satirical internet trend that treats the existence of Santa Claus as an undeniable objective reality while mocking skeptics as irrational 'deniers.' It gained significant traction on platforms like Twitter and Reddit during the 2020 holiday season, often parodying the language used in scientific or political debates. The humor stems from the absurd reversal of roles: the believer represents 'logic and evidence' while those claiming parents buy the gifts are framed as delusional conspiracy theorists. It is widely used to create ironic holiday content that pokes fun at overly skeptical or pedantic online behavior.
