Sedentaryist

Exercising a strict adherence to the religious and or political tenets of or pertaining to a significantly sedentary lifestyle. Expressing (without movement or action) a firm belief in all things lazy and inactive.

Lazy Susan is one of the sedentaryest sedentaryists I know. She is a firm advocate of antidistestablishmentsedentarianism and her quite passion for the sedentary lifestyle borders on sedentarocity.
