sustainer
 n.— «Ms. Clark, 56, is a “sustainer,” in league parlance, meaning she has moved to an advisory position. “I’m an old doll. They need us,” she says of the league’s “active” members, the roughly 28-to-35-year-old core of the club, the young women who put the junior in the league.» —“Old dolls and Junior Leaguers” by Leanne Delap Globe and Mail (Toronto, Can.) May 8, 2004.
