hard figure
n.— «Some might call Clappy a dummy for not taking such a high-profile part in a Hollywood movie. But you’re not supposed to call him that. The proper term is “hard figure,” those in the ventriloquism trade say. Clappy is a ventriloquist’s doll.» —“The Kid Quits the Picture” by Allen Salkin New York Times July 29, 2007.
