The 'That Motherfucker Is Not Real' meme features footage of marketing executive Tiffany Gomas during a viral outburst on an American Airlines flight in July 2023. Gomas was filmed gesturing wildly toward the back of the plane while screaming that an unidentified passenger was 'not real.' The footage quickly became a sensation due to her intense delivery and the mysterious, almost supernatural nature of her claim. It has since evolved into a versatile reaction template used to describe situations where something feels off, suspicious, or completely unbelievable, often paired with humorous captions about social anxiety, hallucinations, or irrational frustrations.
