something about stimming & autism

Does anyone else "stim" by explaining basic things about the media they like over and over again, to others and to themselves? Things that you already know as a basic fact but you just love saying it again and again, or straight up just explaining it like you're a wikipedia article. 

For example, i absolutely love the guilty gear franchise and the characters in particular. And you know what i love to do? Literally explaining every character, their design, a quick rundown of their backstory, their personality, or just basic knowledge like their names and height and stuff. I don't know what drives me to do it other than "i love them all so much i have to talk about them". And it's not even my special interest!! (i think...). I do this for every media that i like, with my actual special interest (dorohedoro) having it the worst because i love recapping the entire manga in my head over and over, with all the details and things that are happening, and idk!! It's just so fun. (mind you this thing is 23 volumes full of absolute chaos)

It's fun and it feels very satisfactory and almost calming? Sometimes when I'm under stress i will literally just start explaining some scene i like from a media, recapping every event To Myself, In My Head lol

If you see this and have your own take on this feel free to share:)) I'd love to hear if this is more common of an experience with autistic people than i think.
