Spinner is a term referring to the fully grown adult insect. Following the final stage from dun to spinner, the emergent adult dries itself again and reserves strength. Usually at sunset is when you start to see the 'dance' as the bugs gather in clouds of thousands. After the spinners dance for a while the female mayflies will deposit there eggs by either an egg sack or landing on the surface and depositing them. Either way this makes the mayfly females vulnerable and a feast for the trout to gorge on. When all the mating and egg laying is over the mayflies die and fall to the waters surface. These make great trout flies as they will feed heavily on the 'spent' spinners.
