A parent who is overly devoted, micromanaging the lives of their children, from the food they ingest to the activities they participate in. Sanctimommies look down their noses at those who are more liberal in their parenting approach.
My mother is a sanctimommy because she won't let me eat any food with partially hydrogenated oil in it. She says it's like eating plastic.
