Rocking back and forth when sitting, also during meals, flapping one or both hands, intertwining and turning fingers and hands, feet and legs shaking, rubbing my head. All kinds of shaking and rocking, picking my shirt and pulling it off the chest. Someone recently told me i make gutturual sounds like i'd hawk or growl but i'm completely unaware of it.
When stressed out, especially due to anger, i repeat single words or sentences for hours, sometimes combined with flapping or rubbing and the only way to stop the cycle is to focus on something else, an activity that requires close attention (or sex. I know how this must sound but it's actually helping me.)
I use homemade squishy toys i.e., balloons filled with some flour, in many different ways like rolling it between my palms, pulling, squeezing, shaking, throwing from one hand to the other, and so forth. That's one of my fav's and i need to have at least one in my pocket when leaving the house.
