A punch to the face, for the purpose of getting someone to wake up to themselves. Can be a back-hander, or an open-handed slap also. As long as it gets the message across.
That bloke is right up himself! Someone ought to give him a good smack in the chops, and tell him to pull his head in.

Get the Smack in the chops mug.
Opening and closing one's mouth in a way that causes the spit within to make audible noise. Occurs during talking or inhaling through the mouth.
Please stop smacking your chops, it is annoying for headphone users to listen to.
