What this wasThe story

Brain rot names two things at once: a category of deliberately incoherent short-form content — surreal edits, AI-generated animals with invented Italian names, layered in-jokes that require hours of context to parse — and the state of mind produced by watching too much of it. The people who use the word are almost always describing themselves.

The genre it names has continued to accelerate, largely through AI-generated video, and the word has been taken up by the same broadsheet commentary it originally satirised. Whether the effects it describes are real is now a live research question rather than a joke.

Why it matteredWhat changed

A phrase Thoreau used in 1854 was Oxford’s word of the year 170 years later, after its use more than tripled in twelve months.
