A non-word that is often accidentally derived from the word 'compulsion' (which is in turn authentically derived from the word 'compel', or 'compelled'). This phenomenon might possibly be more common among fans of Robert Jordan's Wheel of Time series.

Well you see - it is very similar to the act of convulsing, but not. Convulsing is when one is foaming at the mouth like a rapid beast of nature whilst shaking uncontrollably and becoming partially blind. COMPULSE, however, is the very simple act of moving one's body when you do not know what else to do. This very real word can occur while dancing, blacking out or an unconscious habit when one feels extremely awkward.
"Oh my god. Look at that girl starting to compulse on the ground over there. Bitch is crazy!"
