Sack Clack 

The act of being completely naked while thrusting so hard that your balls sack starts smacking against your taint hard enough to make a clapping sound. It is quite and impressive party trick might I add.

Yesterday, my mom caught me doing the sack clack and she started to join in and she was really good at it!

Sack My Cack 

1: A more elegant term used in place of "Suck my cock".
2: The way an angry Bostonian man, one that probably doesn't respect women, would ask for fellatio.

Eey baybee be a darlin and sack my cack while I watch the Red Sax.

Cacky Sack 

A game/punishment similar to hacky sack. The Sack of a man is removed swiftly then stitched crudely with a bone needle or bobby pin, then rolled in a protective liquid to keep the sack from leaking and falling apart after dried by the sun.

Today in PE, Christian made a basket with our Cacky Sack, then so did Julian.

Hitting the sack - When you should be going to bed, but you either don't want to, or would rather crash on the couch...

Opposite of Crackalackin, because there's nothing happening...

*Yawn* I'm knackered. I better get sackalackin...But this sofa is soooo comfy.

Better get sackalackin. I got an early meeting tomorrow.
