A day in a school, usually Middle or High school, where teenagers go around slapping each others butts for the fun of it. Common for a guy to slap a girl's ass, a girl to slap a guy's, or two female friends to slap each other, but is usually taboo for two guys to do so. Normally occurs on Fridays and the message is often passed through a forwarded text.

Get the Slap-ass Daymug. When girls get slapped in the butt by guys. Every Friday it is scheduled. A day when people can slap other people's butts. Girls can slap guys' butts too. Some people do enjoy this day. But it must be very painful for some girls, though.
Today, I noticed it was Slap Ass Friday. I spotted my crush of three years. And As I walked down the hall, I spotted him. Then, I passed by and I quickly slapped his bum with hard, heavy pressure. I could tell he enjoyed it because of his huge smile. It was great pleasure to do that. He blushed as I gave a wink and ran off cafeteria.
