Talking Slows Time

"Don't you find it weird how that bullet fired at us barely moved an inch while I gave my minute-long monologue?"

"Nope. It's just that Talking Slows Time."

When people are talking before a moment that would either (severely) hurt or kill them, that's a cue for God to put time on slow-mo so then they can get their dialogues out of the way. This might or might not prevent the threatening event from happening. This UnTrash may be unintentionally played by creators who weren't paying attention to how much time was supposed to pass during its playing, which results in time seemingly slowing down as the characters talk during the scene.

Compare to Rewinding Cuts. They both disrupt the flow of spacetime in a way that's convenient to the characters being put in harm's way to some extent.
