--- ORIGIN
This idiom is said to go back to the Victorian politician Benjamin Disraeli who, apart from finding time to regularly become Prime Minister, also found time to write a novel called "The Young Duke". In the book there is a description of a horse race in which the two favourites cannot make the running. In the meanwhile "a dark horse...rushed past the grandstand in a sweeping triumph".
The phrase is still used today. In a 2013 pop song, Katy Perry asks, “Do you dare to do this? ’Cause I’m coming at you like a dark horse.” Who knows what rock stars really mean in their lyrics, but we can guess that Perry meant she was an unexpected suitor who would be unexpectedly successful.
