👉 A plainsman, also known as a "plump" person or "fat," is typically defined as someone who has a body mass index (BMI) greater than 25. This means that they are overweight or obese and may have a higher risk of developing health problems such as diabetes, heart disease, and certain types of cancer. While some people might consider themselves plainsmanned for their physical appearance, it is not uncommon to see individuals with a BMI in the "plump" range
