When someone's stupidity is so painful to watch that the pain has to be shared via a open-handed slap to the head.

A stupid craze where the victim is attacked, and the incident recorded. Supposedly against the law, although lots of incidents are not brought to police attention. Is not always to random people, can be someone well known to the attacker, and the violence can be a form of revenge. Not always teenage boys-I was 13 when I was attacked by a girl a year younger.
I was filmed at school having food thrown at me and my friends and then me being slapped. The teacher whose attention it was brought to gave punishment for the violence, not for the happy slap. Through lying and crying, my attacker managed to spread the rumour that I was the attacker, and her the poor discrimated victim.

The act of responsibly using a condom during sex, then, while hiding the fact that you're about to cum, pull out, rip the condom off, and simutaneously slap her in the face with the condom while re-penetrating and cumming in the lucky girls vagina.

Rhythmic, wet clapping noise made by repeated pounding of the loins against the naked buttocks of another while in the shower.
I walked by the locker room and heard the distinct sound of a Sandusky Slap coming from the shower stalls.
