I had to look this one up. Basically "awwtysm" sounds like "autism".

Urban Dictionary: aw tysm

means "aw thank you so much" but when siri or text to speech says it, it sounds like autism.

Thanks for explaining the obvious joke, sherlock
It’s a valuable service. How will the next generation of chatbots write jokes if there isn’t someone explaining every joke.
It’s definitely not obvious, locksher
Is there supposed to be some hidden meaning? Does “tysm” mean something?
“Aww, Thank You So Much.”
