Reactions would include “running on the spot”, cupping hand to mouth and blowing into it, shaking hand violently, yelps of “Aowww” and “Ooya”, deep intakes of breath, puffing and panting, squeezing hand shut and drawing the hand to the chest with eyes closed struggling to suffer the pain.
A number of schools can give reports of group or mass beltings. I saw one in a school one day in the late 60’s which resulted from food being thrown in the dining hall during the lunch break. The throwing spread and eventually the whole place was in uproar and the duty teacher had lost control.
