A slapping of one's head with an open hand or penis. In order to successfully complete a slap
upside the head, the slap must be in an upward motion. The point of contact is usually on the side of the head or occasionally, towards the back and always around the ear. These types of slaps are brought on by those who something completely idiotic, who just don't get it, who
owe money or just don't know how to listen. This variation of the slap is not meant to physically hurt, just insult/demean them and hurt their feelings becuase they are a complete moron or they owe you a lot of money. It can also be used as a type of
dick slap meant to put your bitch in her place.
