Most Wrestlers have to improvise throughout a match
In the world of professional wrestling there has to be improvisation during a match. What’s strange about pro-wrestling is the fact that some people enjoy labelling it as “fake” and entirely scripted, but in truth wrestler don’t get to rehearse for their match’s usually. There’s no second chances for them either, it’s usually the one take and that’s it. It's not like a fight scene in a movie, where the performers may spend weeks working out the choreography, yet every move needs both wrestlers cooperating perfectly or somebody's neck will get broken. That means the performers need to talk to one another.
Ever watch a match and notice how one wrestler will do a move where he's kind of just holding the other guy's head for a bit, maybe in a side headlock or an armbar, for no particular reason? This frequently used move is called a rest hold. Not only does this give the wrestlers a chance to take a breather, but they can also communicate with each other about what the next spots will be. This is either to remind the other wrestler what's coming up.
#10 Batista calls for the Tombstone
On a WWE Bragging Rights PPV, The Undertaker and Batista squared off in a fatal-4-way match.
Coming towards the end of the match the Undertaker hits a chokeslam on Batista. If you listen closely enough to when the footage angles at the undertaker standing above Batista, you can clearly make out the Undertaker asking Batista “You alright?” Batista responds with “No”, and then as Undertaker pins him you can clearly make out Batista telling him “You gotta hit me with the tombstone.”
Its clear that the Animal is hurt and wants to finish the match there and then. It also says a lot about the Undertaker as a performer being able to know when something isn’t quite right.
