A person with multiple diet restrictions, such gluten intolerance, nut allergies, poor methylation, lactose intolerance, etc., or who have adopted severely restricted diets, such as the Whole 30, the Keto Diet, the Paleo Diet, locavore diet, or other prescriptive eating plans. Origin: "Air ferns" are dead and dried hydrozoans that were popularized in the 1970s as low-maintenance house plants that required no food or water, only air.
It's impossible to plan a holiday dinner with all of the air ferns in my family; I can't cook a single dish that everyone can eat.
