The TMFINR meme, short for 'That Motherfucker Is Not Real,' originated from a viral video recorded on an American Airlines flight in July 2023. In the clip, passenger Tiffany Gomas is seen walking down the aisle, visibly distressed, as she points toward the back of the plane and screams that a fellow passenger is not real. The video's intense energy and mysterious context immediately captured the internet's imagination, sparking countless conspiracy theories and parodies. Users now use the template to humorously call out things that seem suspicious, uncanny, or simply too good to be true, often replacing the 'not real' entity with celebrities, fictional characters, or relatable everyday inconveniences.
