Aaaand cue the police sirens in the distance, then Alice running with her hair on fire and a small angry chihuahua with its jaws tightly clamped on her leg, and the entire neighborhood chasing after her with Torches and Pitchforks.
Essentially, this is when when a character pretty much knows something or someone well enough that they can predict what going to happen AND point at the exact time when it does, to the point that they might just look at their watch and count down the exact seconds until the inevitable happens. They're not psychic or anything, it just common situational awareness and good timing.
This trope is often played for laughs, and it doesn't always have to be between two people; sometimes a character is familiar enough with a particular situation, along with their luck, to accurately guess where it's going. Heck, characters may be so good at it they don't need to have a watch around.
- In Pokémon: The Original Series, "Island of the Giant Pokemon", Ash, Misty, Brock and Team Rocket end up on a mine cart where they're reunited with their Pokemon while dragging a few huge Pokemon (really robots) behind them. When Ash wonders what they can do, both Jesse and James, no strangers to bad luck, pretty much predict what'll happen next. Namely their cart will go off the rails, the line snagging the giant Pokemon will snap, they'll crash into something and they'll get flung into the sea. And indeed, one by one, that's what happens the moment they call it.

Doc Tofu advises Ranma that there's a more genteel side to Akane, and cleverly smacks Ranma above the sacrum as Ranma departs. After a few minutes, Doc Tofu eyes his clock, and counts down the seconds to zero, at which point, Ranma suddenly loses the use of his legs. Akane offers to carry Ranma piggyback to the Tendō home.
