The 'Boys Sleepovers vs. Girls Sleepovers' meme is a popular comparison format that uses humor to highlight perceived differences between how genders spend their nights together. Typically, the 'Girls' side depicts a wholesome, emotional, or organized activity like face masks or pillow talk, while the 'Boys' side showcases chaotic, surreal, or high-octane scenarios involving gaming, wrestling, or historical reenactments. Emerging in the late 2010s across platforms like Twitter and Reddit, the format evolved from simple text comparisons into elaborate visual montages. It relies on hyperbolic stereotypes to create relatable comedy, often framing the boys' activities as an absurd brotherhood ritual that defies logic and physics.
