The jiggly argument is about not all parts moving at once or in one direction. If you jiggled to the right by taking one 18 inch step to the right, sticking your left arm straight left, waiving your right arm in a complete circle, holding your left foot 3 inches off the ground, and squatting down 10 inches how far have “you” moved?
The answer by the thermometer is the temperature, which is based on more degrees of freedom. You’ll have to define some mapping between the other degrees and velocity.

How does the thermometer get its answer? I’d measure that part.
