Brainrot

The term itself predates the internet: the Oxford English Dictionary traces 'brain rot' in print to 1854, when Henry David Thoreau used it in Walden to lament a society that prized 'easy' ideas over difficult ones, asking why a culture would let its brain 'rot' through under-stimulation.

The modern internet sense re-emerged on forums like Reddit in the early-to-mid 2020s — communities such as r/BrainRot and r/TikTokCringe began using it to describe the experience of mindlessly consuming reels, Shorts, and 'subway surfers gameplay + Family Guy clips' split-screen videos for hours.

The term exploded alongside the rise of 'Skibidi Toilet' (2023), 'Italian Brainrot' AI-animal memes (2025), and similar hyper-absurdist genres aimed squarely at algorithmic feeds. In December 2024, Oxford University Press named 'brain rot' its Word of the Year, citing a 230% year-over-year increase in usage and noting its adoption by Gen Z and Gen Alpha as both a self-deprecating joke and a genuine cultural anxiety about attention spans, algorithmic addiction, and the erosion of shared cultural reference points.

On Reddit, threads in r/OutOfTheLoop and r/TikTokCringe regularly attempt to catalogue the ever-shifting glossary of brainrot slang (Skibidi, Gyatt, Fanum Tax, Ohio, etc.), treating it less like vocabulary and more like field notes on a fast-mutating digital subculture.
