I do a lot of things. I knee-bob (I've always called it knocking my knees), I'll chew my lip raw, I do a hand motion where I crack the knuckles of my four fingers with my thumb over and over, I'll run my fingers through my hair repeatedly, when I'm in meltdown mode I'll start to claw at the skin on my arms, and I've come to notice that sometimes I'll randomly say "meow" completely unprovoked.
I don't know if these would be considered stims but I do/have done these things on a daily basis and don't feel right if I don't do them. I find myself needing to be extremely active during the day. Subsequently I've done things like swing on a swing set or jump on a trampoline repetitively, for hours. HOURS!! My biggest stim of this sort is pacing. I've paced for as long as I can remember. I section off a certain part of the house/room and I walk back and forth, in a circle, etc. in a pattern that feels right until I get tired of it and then I go and find myself a nice activity to do. At one of the old houses I lived at, I wore a circle into the wood on the deck from where I would pace. I have to do this for a few hours a day otherwise I will get incredible antsy, cranky, and above all, unproductive. It eats into my time too but it's better than sitting there being unable to do nothing because the thoughts in my head are flying around so fast. I've started to walk around town to try and curb this and wear me out a little faster but I just got back form 30 minutes walking back and forth in my bathroom so...obviously not helping.
Oh, embarrassing stims too now? Ok, when I was a kid, I humped chairs. That's right. I humped chairs. Now nobody can feel embarrassed of their quirkier stims because hey, at least you don't make love to recliners.
