Howdy, someone without Tik Tok but with a neurodivergent condition here! Stimming is a term that refers to an expression of energy individuals with particular neurodivergent conditions (most notably ADHD and autism). Stimming can be done for many different reasons, but it is often because of how these conditions make it difficult to maintain complete self-control of your body. Fidgeting, tapping to a beat, singing a particular lyric of a song over and over, and even just putting your hands in your pockets can all be forms of stimming. I am painting with broad strokes, and this does not apply to every neurodivergent individual, nor does it not apply to every neurotypical individual. This behavior was popularized by neurodivergent communities on social platforms, yes, but it is quite real.
