Brainrot
Brainrot is kids' slang for absurd, repetitive, endlessly scrollable online content, and also for the foggy feeling of watching too much of it; it's mostly a harmless in-joke, with the main concern being how much time it takes.
Should I worry?
There is no specific danger here. The concern is the same as with any endless feed: it can crowd out sleep, homework and offline time, and kids can feel flat or scattered afterwards. Watch for a child who seems unable to stop scrolling, is irritable when the device is taken away, or has lost interest in other things. If you see that, talk about how the feed makes them feel, and agree together on screen-free moments, such as at meals and before bed.
How to join in
Brainrot is the label kids give to deliberately silly, nonsensical memes, odd characters and repeated catchphrases that spread fast and are funny mostly because they make no sense. Kids enjoy it as a shared in-joke and as slang they can use to tease each other. It was even named a word of the year by a major dictionary, and Québec language experts have suggested French alternatives such as « écervelage » or « abrutissement numérique ». A good way in is to ask your child to explain a meme or phrase they like and why it's funny, then laugh along. You'll learn more from that than from any article.
Try saying
“I keep hearing the word brainrot. Can you show me one that makes you laugh? And if you ever notice your head feels fuzzy after a long scroll, tell me, and we can figure out a break together.”
