I assume that you mean something similar to the intro that Man At Arms uses in their videos?
Example here: https://www.youtube.com/watch?v=V0_qu4e5Gs4
Since the audience cannot pause the movie at the theater and only a bunch of anal retentive nerds in the world will actually pause their DVD or streaming to read the messages, you can say simply say that more and more social media posts pop-up covering the hole screen/everything, etc.
Maybe focus on the message that pop-up last, if it is important, and describe what it says.
What the other messages say is up to the editors and graphic designers. Why not give your work to others when you can?
If you are going to do this work yourself however, it would be a great idea to put references, jokes and Easter Eggs in them, so that the nerds will be happy to find out that they found something unique.
