Walter Mitty

Walter Mitty
A person, generally quite ordinary or ineffectual, who indulges in fantastic daydreams of personal triumphs. For example, He's a Walter Mitty about riding in a rodeo but is actually afraid of horses. This term comes from James Thurber's short story, The Secret Life of Walter Mitty (1939), describing just such a character.
