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.
FWD: Fwd: Friday is Slap-ass day! forward to all members of *name random high or middle school* in your contact list!

A wholesome day hosted each year on October 29th. Whether you're the Griffin getting slapped, or slapping that same Griffin, at the end of the day, no ones actually harmed so don't be a little shit about it.
Person 1 "Hey Griffin! It's October 29th! You know what that means."
Griffin "OW! Haha, I sure do love Slap Griffin Day!"
Griffin "OW! Haha, I sure do love Slap Griffin Day!"

Slap Griffin Day was on October 29th. It's very epic.
Me: "I'm so sad, we missed Slap Griffin Day..."
You: "We did?! But it's my favourite holiday!"
Griffin: "HOhmygAWD"
You: "We did?! But it's my favourite holiday!"
Griffin: "HOhmygAWD"
