Broke hot is when an overweight woman gets dumped for not loosing weight, but then is forced to lose weight as a result from not having her ex boyfriends resources.
Jane was eating too much ice cream and refusing to lift a finger around the house, so Henry dumped her. Because Jane was inherently lazy and unable to get a job quickly she lost 40lb's having only food stamps to afford her the essentials. Shortly after attaining a normal body weight, Jane was considered hot again and she was able to find another man. Jane became Broke Hot.
