chin smack 

Using the top part of your hand to smack your girlfriend under the chin because she said something obvious.

Her: it's so hot out here I wish I would have put on sunscreen!

Him: I warned you before we left the house you should have put some on and you didn't listen. You deserve chin smacks. (Smack smack smack)

Chin Sack

Chin sacking is balling your fist up and putting the hollow of your hand on a person’s chin, which resembles a scrotum. If done to a person who doesn’t know what’s going on its pretty funny. (tell them what it means afterward.)

try doing the chin sack on someone.
