Sack Shadow

The untanned spot left on your inner thigh from where you testicles (aka ball sack, balls, sac, bag etc...) were lying when tanning or nude sun bathing.

"I kept moving my balls around while tanning to prevent sack shadow."

"I hate when I see him in briefs, his sack shadow is obvious."

potato sack

Potato sacking is much like tea bagging except that it involves a much larger set of testicles.

Chuck Norris doesn't tea bag ladies, he potato sacks them!!

Sack Hammock

A holster for a bulls testicular sack during castration. The sack catches the testicles upon removal allowing for clean and safe transport of said testicles.

Farmer: Thank God for this sack hammock or I'd be picking up these nuts off the ground with my hand.

Thunder Sack

Thunder sack is when a man is sitting down, and blows ass so hard it rumbles his balls.

I was sitting on the couch the other day, and made a nice thunder sack.
