The term 'Fold of Skin Under the Throat' can be summarized as a DEWLAP, which is a 6-letter word. A DEWLAP is a fold of loose skin that hangs from the neck or throat of certain animals, such as cows, horses, and some lizards. It is believed to have evolved as a way to help regulate body temperature, as it can be used to dissipate heat. In humans, a DEWLAP is usually a sign of aging, but can also be caused by genetics or weight gain.
