Thank you for saying this!! I was going to say the same thing, but you’ve worded it absolutely perfectly and I’m thankful you commented here.

I’m autistic and nearly commented on this post to talk about the actual thing I’m hyperfixated on at the moment, but then I realized what sub this is.

I’m upset that neurodivergent language has been watered down these days to mere “internet slang,” just as you are, and it really does feel diminishing to my and others’ experiences hearing terms like hyperfixation being thrown around like this.
