Meaning
A person, group or product whose ability or appeal rests on a single talent, skill or feature, with little range beyond it. It is usually said with disappointment or as a warning that success depends on one narrow capability that may not last. Informal and mildly negative, implying limited range even when the single skill is impressive. Regional use: General English (originally American).
Origin
The image is literal: performing ponies in circuses and sideshows were sometimes trained to do exactly one trick, so the animal's entire value lay in a single routine. Etymonline dates the figurative use to 1897 in American English, in reference to circus acts, and Grammarist likewise traces the metaphor to circus and sideshow acts of the late 19th and early 20th centuries, when a pony might perform one specific trick, sometimes simply playing dead. Audiences were impressed at first but soon realised the pony had nothing else to offer, which is the point of the metaphor. The term has since spread far beyond entertainment to politics, sport, business and technology.
