This is where a work is adapted, then the adaptation is adapted, and so forth. The adaptations pile on a ridiculous number of times, usually resulting in the actual source material appearing completely unrelated.
This is often done to capitalize on a popular franchise, especially when an expired copyright is involved...
It's important to note that this is not necessarily a bad thing, as the adapted works sometimes end up being genuinely good, or at least lucrative.
This trope often results in (and is not to be confused with) Recursive Adaptation, Adaptation Displacement, Lost in Imitation, and Adaptation Overdosed.

- Fifty Shades of Grey is an interesting case, being an Ascended Fanfic rather than an official adaptation. It all started with a dream Stephenie Meyer had, which inspired The Twilight Saga, which was adapted into a film series. That inspired an erotic fan fiction by E. L. James, which became a novel series, which got adapted into its own film series. Then that inspired a romantic comedy with its own sequel in the works. Fifty Shades of Grey also heavily influenced 365 Days, a trilogy of erotic romance novels published by Polish author Blanka Lipińska which contains the same themes and concepts, in addition to being adapted to the big screen.
