What is brainrot?
Brainrot (also written brain rot) is internet slang for the foggy, can't-focus feeling that comes from too much low-effort content: endless short videos, doomscrolling and handing small bits of thinking to your phone. People use it to joke about their own attention span, and to describe the absurd meme-speak that spreads through short-video apps.

Where the word comes from
The phrase is older than the internet, but it took off on TikTok, Instagram Reels and YouTube Shorts in the 2020s. In December 2024, Oxford University Press named “brain rot” its Word of the Year, describing it as the supposed deterioration of a person's mental state from overconsuming trivial online content.
Everyday signs of brainrot
- 01You open an app, close it, and open it again without noticing.
- 02Anything longer than a minute feels long, so you skim or watch at 1.5x.
- 03You reach for a calculator for sums you could do in your head.
- 04You search for a name or fact before you even try to remember it.
- 05You pick up your phone first thing in the morning and last thing at night.
- 06You understand, and maybe use, words like skibidi, rizz and gyatt.
Is brainrot real?
Brainrot is not a medical condition, and no test can diagnose it. What is real is that skills you stop using get less practice. If a calculator does every sum and a search bar holds every fact, doing those things yourself starts to feel harder. If you are worried about real changes in your memory or concentration, talk to a doctor rather than a quiz.
How the Brainrot Meter measures it
The Brainrot Meter is a 90-second brainrot test with 12 questions across four areas: attention span, memory, mental math and scroll damage. Some are tiny tasks, like counting letters or remembering a number sequence. Others ask what you actually do, like your first move after waking up. Each answer adds 0 to 3 points, and your total becomes a brainrot percentage from Certified sharp (0–30%) to Fully cooked (81–100%).
How to lower your brainrot score
Make the first attempt yourself. Do the sum in your head before you check it, try to remember a name before you search for it, and read a whole article before asking for a summary. Short daily practice, like a few minutes of mental math, keeps those skills in use.
