a gluttonous, egotistical, insecure slob who eats an uncontrollable amount of food and claims to be an athlete. these sports acclaimed to be his/her calling may be soccer, basketball, or lacrosse. One might even overdress for certain occasions because of its insecurities. A Diseased Fatass is often prude and lazy. They even act black and hate on everyone else around them.
