I'm ASD with mild Turrets, and often when I'm stimming, it includes reenacting things I found funny on TV and stuff like that, so sometimes I worry about saying some inappropriate or weird stuff out in public like "I WANT THAT MULAN SZECHUAN MCNUGGETS SAUCE, MORTY!" and stuff like that, so I kinda whisper or mouth it. SpongeBob quotes are also a common stim I have too, including "GOOD GREIF, HE'S NAKED!" and "you like Krabby Patties, don't you, Squidward?"
Does anyone have similar experiences with stims?
