hailstorm

When a phenomena occurs without any planning or communication, and is executed perfectly by multiple participants as if planned.
John and Joe walk up to a control box with two buttons. John and Joe look at one another. Nod, say "Hailstorm." And then in unison push both buttons at the same time.

John and Joe walk up to a cliffside. John and Joe look at one another. Nod, say "Hailstorm." And they both jump into the water below at the same time.
