When you have your erected penis out and a group of people repeatedly slap it all at once until they either get tired or when it falls off, and by it i mean your peanits.

A woman's booty that is so big that if you were to vertically slap the booty at a 90 degree downward angle, three of your fingers and 75 percent of your palm would connect with ass
Damn Mike, you see that downward slapper over there?! I bet she could make that shit clap for days!
Hey bro, Mike started seeing a new girl, but she don't got a downward slapper. That shit ain't cool.
