Brain rot
Slang for low-quality online content and its mental effects
In the Ark and going to the Arctic.
“Thoreau used it first, in 1854. It took TikTok to get it made Oxford's Word of the Year in 2024.”
Why Noah kept it
Brain rot is what people called the junk they couldn't stop scrolling, and what it did to their heads. Oxford made it Word of the Year in 2024. Skibidi Toilet and Italian brainrot are in the Ark as examples. This is the word that people used for the whole thing, so a reference goes in.

What it is
Brain rot is slang for poor-quality digital media, particularly short-form videos, AI-generated content and doomscrolling. The term, traced back to Thoreau's 1854 writing but popularized on Twitter and Discord from 2007 onwards, exploded in use from 2023 to 2024, becoming Oxford's Word of the Year in 2024. People used it to describe both the content itself and the cognitive damage of consuming it.
Why it’s internet culture
The term shows how young people online became conscious of their own attention being harvested by platforms and low-effort content, and how they named the feeling of mental decline from endless scrolling. It also tracks the shift from criticising specific bad shows or movies to treating the entire structure of social media as the problem.
People, mostly young, named the low-effort content they kept scrolling and the foggy feeling it left them with, then used the label as a joke about themselves. It's slang that started online, got into Oxford's Word of the Year in 2024 and was picked up by psychologists and parliaments.
Noah’s field notes
What someone in two hundred years would need to know to understand it.
Originated Online slang, mainly TikTok, Discord, YouTube and Twitter; the phrase itself is first recorded in Thoreau's Walden (185… · Also known as Brainrot; brain-rot
- What it is
- Brain rot (often written brainrot) is English slang with two meanings. It names cheap, repetitive, often nonsensical videos and posts that people watched in huge amounts on their phones, usually by swiping through an endless stream of short clips picked for them by an app. It also names the dull, scattered feeling people said they got from watching too much of it. People mostly used it about themselves, half as a joke and half as a complaint.
- Where it came from
- The phrase is old. Henry David Thoreau wrote 'brain-rot' in Walden (1854), comparing a taste for trivial ideas to the potato blight. Online, people reportedly used it from the late 2000s about reality dating shows, video games and spending all day on the internet. It spread widely between about 2020 and 2024 on Discord, TikTok and YouTube, where it got attached to the nonsense slang children picked up from short videos. Oxford University Press made it Word of the Year for 2024, saying its use rose 230% between 2023 and 2024.
- Why it mattered
- It gave people one word for a feeling plenty of them shared: their phones were filling their time with rubbish and they kept watching anyway. Because the word was self-mocking, people could admit the habit without sounding preachy. The word then moved well beyond the joke. Psychologists and mental health groups used it when writing about attention and screen time, and in 2024 the Australian senator Fatima Payman gave a short speech in parliament in the slang of Generation Alpha (children born from about 2010). A joke label ended up in dictionaries and political debates.
- What noah thinks it shows about us
- People knew the endless video feeds were bad for them and said so constantly, usually while still scrolling. Turning the complaint into a joke made it easier to talk about the habit and easier to carry on with it.
