The tone depends a lot on who says it. Parents often mean danger, teens often mean lol my attention span is gone, fandom people sometimes mean yes I am obsessed and I know it.

One learner trap: My brain is rotting is meme talk. My brain is sick is medical sounding and not the same. I wouldnt use brain rot in a doctors office unless I was making a joke.

You can attach it to a source too: Fox News brain rot, TikTok brain rot, manosphere brain rot. Then it means the whole feed has cooked someones judgement, not just one meme.

I teach 7th grade and the kids use brainrot for the language too. If they say brainrot words they mean skibidi, rizz, 6-7, aura, sigma, that whole packet of references.

Italian brainrot is a whole side branch now. It is those AI animal-object things with fake Italian-sounding names, not really memes about Italy or actual Italian vocabulary.

Brainrotted is the adjective people reach for. A kid saying I'm brainrotted by Skibidi is joking about himself. An adult saying these kids are brainrotted usually sounds way more judgmental.

In fandom spaces it is not always an insult. Somebody with Dune brainrot or K-pop brainrot may just mean they cant stop thinking about it. More like embarassing obsession than low quality content.

Spelling thing I see a lot: dictionaries are still mostly on brain rot, two words. Online brainrot is totally normal though, especially before a noun, brainrot video, brainrot humor, brainrot slang. For school writing I would keep the space.
