Rock Knockers

The basketball hoop used in Australia with no backboard
The nickname 'Rock Knockers' were given to these hoops because Australian outback heat caused normal basketballs to explode, so people threw rocks at the hoops causing a knocking sound to occur hence the name 'Rock Knockers'

Rock-knockers are like butterslaps.

All ne'er-do-wells call diamonds "apples." Like callin' money "bread" or rock-knockers "butter-slaps."

rock out with your knockers out 

When a woman with big knockers is at a concert and pulls out her tits. May also describe a woman rocking out with her tits out while listening to a song. Similar to rock out with your cock out.

This babe with huge knockers rocked out with her knockers out at the Slayer show!

I want to see all you girls rock out with your knockers out!
