Is anyone else bothered when people refer to being autistic as “the tism”?

I don’t know exactly why it bothers me, but I think it’s because that term is usually used by NT’s on tiktok or instagram commenting on people’s post usually saying “I think you got a little bit of the tism”, usually in a negative way. First you can’t be a little bit autistic, you either are or not, second it’s usually a way to make fun of someone that is different or “quirky”, third I feel like if its not NT people saying it, it’s the self dxers that say that because they literally get all their information and dialogue from tiktok.

For me it gives the same vibe as people calling being autistic “acoustic” which really really bothers me because again it’s usually used in a negative way or again to make fun of someone, it also bothers me because it makes autism or autistic seem like a dirty word which I really don’t like.

I don’t know I could be the only one that is bothered by it? I guess it just kinda feels like a pet name or trendy slang for something that isn’t a trend, I wish I could find better words to describe why I don’t like it but it just kinda rubs me the wrong way, why can’t you just say autism or autistic? It’s like saying “I got some of that polar” talking about being bipolar or “I got that phrenia” talking about schizophrenia which to me is pretty offensive and just sounds like it’s making fun of it.

Would love to know how others feel and I’m open to hearing why you call autism “the tism” if you’re someone who does.

Edit: it was brought to my attention that I shouldn’t refer to non autistic people as neurotypical and to use allistic, or non autistic instead, I want to apologize for using neurotypical, I was diagnosed recently and have only heard people using neurotypical so I was under the impression that was the correct terminology to use, I have never heard of the term allistic before so I am going to educate myself better and use that from now on. I’m so sorry for saying neurotypical and will not continue saying that when referring to non autistic people, I will also continue to educate myself on what is right or wrong but that can sometimes be difficult for me as it seems everyone has varying opinions.
