- n. Heavy tickling often leading to laughter.
Sorry, no etymologies found.
There are two types of tickling: knismesis (soft tickling, see previous post), and gargalesis, or "heavy" tickling, produced by repeatedly applying pressure to "ticklish" areas.
It's been suggested that gargalesis tickling is a way for the touch of the parent to be associated with pleasure, developing a trust-bond "so that parents may touch a child, in an unpleasant way, should circumstances develop such as the need to treat a painful injury or prevent harm from danger."
