Not every game has one, some games have more than one.
My fave is probably No Good Gofers "Hole in 1 shot" but I still have a soft spot for SF2's 2 part skill shot. Timing the launch and then "use the flipper to hit the bracelet target" . Probably the only time those 2 games are mentioned in the same sentence in a positive light.
Are there any really cool or unique ones that we should all know about?
