Realized I have this random stim

I used to do this all the time when I was younger and probably stopped cause when someone noticed they thought it was weird. But I’m just sat at my desk at work interning to music while working and i obviously can’t get up and dance but all this energy was building up and my thigh muscles starting dancing. Like, I dance just with my quad muscles. Bouncing up and down, left and right. Does anyone else do this or have something else they rediscovered?
