That is rather hard to say considering all ships have their ups and downs like regular relationships. But my most hated one has to be... ummm... Flashlight. I'd hate for anyone that does like this ship to hear it but, this ship is nonsense. Twilight is supposed to be the last of the main six to actually have a love interest! Besides she has too much princess work to actually be worrying about love. That is kinda Princess Cadence's job after all
