Shaking

Definition and stakes

L. N. Fowler,  The Illustrated Self-Instructor in Phrenology and Physiology

“ The shake of the head is the natural language of Combativeness, and means no, or I resist you. Those who are combating earnestly upon politics, or any other subject, shake the head more or less violently, according to the power of the combative feeling, but always shake it slightly inclining backwards; while Destructiveness, inclining forward, causes a shaking of the head slightly forward, and turning to one side. ”
