Käämätä
Käämätä is a Finnish verb that translates to "to wriggle," "to squirm," or "to writhe" in English. It describes the motion of something moving in a twisting, undulating, or contorted manner, often due to discomfort, excitement, or an attempt to escape. The word can be used to describe the physical movement of animals, particularly worms or snakes, as well as the involuntary movements of humans when experiencing strong emotions or physical sensations.
For instance, a child might käämätä with excitement when anticipating a treat, or an earthworm might käämätä
