A granny slap happens when a grandmother approaches you and pinches your cheeks so hard that the skin
literally slaps against
your face when released. It is usually accompanied by much cooing and statements that include but are not limited to: "Oh, you've grown so tall," or, "You're my little
sugar bunny!"
John:
Did you see that mark on Jack's cheek?
Jill: Yeah, he totally got granny slapped
yesterday. His sister told me
all about how his skin snapped into place.
