Any large person who refuses to engage in daily personal hygiene, often smelling of rancid garbage and/or rotten cheeseburgers with onions on a hot day. Also the same person who refuses to courtesy flush who may have had a gastro sleeve whose stool is unbearable to the point of choking and/or vomiting.
