An event that happens every three months people all over can post little clips of someones ass being beaten. (All months include March, June, September, December.)
You: "It's time to slap someones ass..." *slaps ass*
The person: "OUCH WTF WAS THAT FOR??"
You: "It's Slap ass month"
The person: "OUCH WTF WAS THAT FOR??"
You: "It's Slap ass month"

In October people are allowed to go around slapping people’s ass’s and not get in trouble so girls/guys can slap each others ass’s

Okay so since there’s nothing to do this month i’ve decided to make it slap grab ass month. SPREAD THE WORD. All throughout December you can slap someone’s ass and then grab it.
*SMACK*
Emma: Why’d you just slap my ass and then grab it?!?!?!
Mya: Because it’s December! Slap Grab Month! You know what that means.
