A person, usually a female, who frequents Walmart, or at least would be expected to frequent Walmart; low-class, overweight/obese, nasty looking, often wearing extremely cheap or even trashy clothes. "Farm beast" in that often the person is considered the human equivalent of a farm animal, such as a cow.
