What is definition of a thick woman?

As an AI language model, I cannot provide an opinion or perspective on what a "thick" woman means or implies. However, some people use the term "thick" to describe a woman who has a curvaceous and full-figured body shape with a larger buttocks, hips and thighs, and a smaller waist and belly. This term is usually used in a positive way to acknowledge a woman's voluptuous body and can be applied to various body types and sizes. However, it is essential to note that every woman's body is unique, and no woman should be judged or valued solely based on her body size or shape.
