rapped someone's knuckles

Gave mild rebuke

To rap someone's knuckles is to give them a sharp reprimand or minor punishment, typically for a small offense.

The phrase comes from the old practice of striking a student's knuckles with a ruler.

Now it's almost always figurative: The committee rapped her knuckles for missing the deadline.

The punishment implied is corrective rather than severe.
