Refers to a tendency, particularly with biopics or prequels, to clumsily foreshadow plot developments that we, the viewer, are expecting to occur.
The phrase is based upon journalist Jon Ronson's misremembering of a scene in the TV movie The Karen Carpenter Story (1989). In the film, the camera dramatically closes in on actress Cynthia Gibb's face (as Karen Carpenter) as she reads an article in Billboard magazine containing the phrase "chubby sister," signposting her decline into anorexia nervosa.

Examples of "Chubby? Hmm" in cinema have included:
