The term "pinchable areolas" refers to the female nipples, specifically emphasizing their soft and plump appearance. In a porn video context, it typically suggests that the woman has large or protruding nipples which are visually appealing and possibly sensitive to touch. These areolas are described as being pinchable because they are soft enough to be gently squeezed between two fingers without causing pain or discomfort, adding an element of sensuality and arousal to the scene.
