How it's used
This idiom is a hyperbolic way of saying someone is exceptionally clever or quick-witted. The literal imagery suggests that even if a ghost were to strike or haunt someone, they would still be alert and sharp enough to handle it. It is almost exclusively used to praise someone's sudden insight or consistent mental agility.
Examples
He is usually so sharp, why is he acting so stupid today?
