It’s not? I never realised. What with the fact that there is a thing called kayfabe and wrestlers writing books, which of course I have never read, since I am obviously too stupid to realise that it is “fake”.
And the term is scripted, not “fake” last I checked, Finn Bálor did dislocate his arm, Seth Rollins did tear the fuck out of the muscles and ligaments in his knee, Daniel Bryan did get so many concussions he had to retire before he became permanently brain damaged, Owen Hart did fall to his death in the ring and Chris Benoit did give himself so many concussions he ended up having permanent brain trauma, which led to his…actions at home, for the lack of a better term. Scripted with pre-determined outcomes is the term you are looking for, and yes, I know, and yes I still like it.
