Percussive maintenance 

The act of smacking or otherwise striking something in order to restore its functionality. While it's success rate is questionable on electronic devices it seems to work more reliably on women.

from the word Percussion-to strike sharply
and Maintenance -to fix
Usually a quick sharp slap to the back of another's head.
usually delivered to stop said person in their tracks so as not to continue their stupid chatter or activity.
