Have you ever experienced brain rot? You almost certainly have, even if you didn’t know it by that name. Brain rot can be triggered by something as simple as watching too many cat videos, or memes, or mindless TikTok videos.
BRAIN ROT
Oxford Languages, publishers of the famous Oxford English Dictionary, define brain rot as “the supposed deterioration of a person’s mental or intellectual state, especially viewed as the result of overconsumption of material (now particularly online content) considered to be trivial or unchallenging.” And in December 2024 they announced ‘brain rot’ as their Word of the Year (WOTY).
Reflecting the year
The tradition of choosing a Word of the Year began in 2004. Since then, every year, expert lexicographers from Oxford Languages select a shortlist of words that have seen a big increase in use during that year and that seem to reflect the concerns of the time. The public then gets to vote for their favourite word. In 2019, for example, the Oxford Languages’ Word of the Year was ‘climate emergency’. And in 2021, when Covid vaccination was still on everyone’s mind, their Word of the Year was ‘vax’.
Tracking how much a word is being used online during the year is one way lexicographers make their choices for the shortlist. This year, data analysis showed a 230 per cent increase in the use of the term ‘brain rot’, especially among young people, and above all on TikTok. Oxford Languages points out that although the term has seen a sudden increase in popularity, it isn’t new. The first recorded use of ‘brain rot’ was back in 1854. American writer and philosopher Henry David Thoreau used it in his book Walden to criticise the way his contemporaries seemed to be abandoning complex ideas in favour of simplistic ones. Thoreau wrote: “While England endeavours to cure the potato rot, will not any endeavour to cure the brain-rot — which prevails so much more widely and fatally?” It seems that every age thinks cultural standards are in decline.
Brain rot in action
Semantically, the term ‘brain rot’ is quite a flexible one. It can refer to the alleged effect of low-quality content on the brain, e.g. “I can’t watch any more of these vids, I’m getting brain rot.” But it can also refer to the low-quality content itself: videos can be ‘brain rot’ (as a noun or an adjective). There are Youtube channels and TikTok hashtags with names like “Most Brain Rot Video”.
Although brain rot is now being used in mainstream journalism, it was Gen Z and Gen Alpha who were the first to identify and name the concept. And they are simultaneously the biggest creators of what they themselves call “brain rot content.”
The 2024 shortlist
Before you’re tempted to check out #brainrot on TikTok (and believe me, life is too short), let’s take a look at the five other words that the experts at Oxford Languages chose for this year’s shortlist.
lore
This word has been used for centuries to mean a collection of traditional facts about a subject. But recently ‘lore’ has become a popular concept on online fandoms, where fans show off their comprehensive knowledge about a particular celebrity.
demure16
The adjective ‘demure’ has been used in English since the late 1400s and means being serious and modest. ‘Demure’ as an adjective to describe an understated fashion look went viral in summer 2024 when American TikToker Jules Lebron used it in a post about how to dress for work.
dynamic pricing
When the pricing of a product or service varies to reflect demand, it’s said to be dynamic. This is a direct translation of a concept in Swedish, ‘dynamiska prisbildning’. One obvious example of ‘dynamic pricing’ is the pricing of flights, which can vary enormously depending on when you want to fly.
romantasy
This blend worddescribes a fiction genre that combines a romantic storyline with elements of fantasy, such as magic and the supernatural. The word was first used in 2008 but became popular in 2024 as TikTokers used it in video posts recommending romantic fantasy books. The website Goodreads has a list of recommended romantasy reads.
slop19
Similar in some ways to ‘brain rot’ content, ‘slop’ is low-quality AI-generated content published online. It could be text generated by a Large Language Model (LLM), such as ChatGPT, or AI-generated video or images. Again, ‘slop’ isn’t a new word but it has been adapted for the digital age. From the mid-1800s, ‘slop’, or the adjective ‘sloppy’, was used to describe low-quality cultural material, especially very sentimental material.
Keep up!
As we’ve seen, several of the words on the shortlist aren’t new but they have been given a new energy through social media. The English language is changing from minute to minute and when a new word catches the public imagination on social media it can spread at lightning speed.
