Drumming to a random beat on a hard surface also I "knot" my fingers

wha-

Cross all my fingers at once

I use my other hand to cross the pinky and ring finger

Same

Fidgeting with my lucky bracelet

nice :D

random movements tbh i can't really describe mine

i think i do that too-

it's the peace and tranquility dance from ahit

honestly i thought stimming meant something you'd do in modern warfare

no

making weird duck noises in class

LOL

haha gay

chewing on my headphone audio cord
smelling stuff
tapping my foot/ feet when sitting
anything to deal with my hands (like typing!)
music
messing with my hair (which I wish was shorter)

random noises i pick up from EVERYWHERE and I mean EVERYWHERE (today's noise is from TOH: kings 'weh' and maybe 'HEH')

thank you for coming to my tedtalk

not me making Giovanni noises

also the bipper arms thing-
(the 'bipper does arm things' post will provide context)
wear my headphones and tap them
goblin hand thing

YES THE STUPID FOOT TAPS ALL THE TIME

hand flaps

I usually smile like a dumbass while doing so but not a requirement

kicking your legs agressively

AAA SAME

PLEASE SUCH A HAPPPY STIM

Creating chaos

grabbing a plushie by the face and squishing its face as if i hate it (i actually love it and would die for it)

i sometimes cry into a plushie

Fidgeting. With anything.
Playing with bracelets, elastic, or hair ties
