   “Coordinate term: stimming”

   “Medical culture constrains stimming through strict clinical designations and pathologizing definitions, referring to it as stereotypies or "self-stimulatory behaviours." Autistic people, however, often define stimming more broadly as repetitive sensory practices used to regulate emotional states, to cope with external sensory stimuli, or for purposes of self-expression.”

2. (uncountable)The process of making stereotype plates and printing from them.
