This man asked his wife to slap him awake every day for 15 days. (We don't know why.) She filmed it every day. This sounds like it could get old. It doesn't get old. It gets amazing. Just watch.
The slap has been a thing of beauty since it's inception. Five fingers to the face can mean many things...if you're a rapist. Most people know that you've gone too far when you get slapped. Of course, some ladies bust out a slap for any occasion, but they have issues, and it's probably best if you stay clear of them...
