Back Sack

Male equivalent of the side boob. When someone gets a glimpse of your sack from behind. The worst angle to see balls, which are quite frightening at any angle.

That asshole Carl tricked me into looking at his back sack yesterday!

Hit the sack out of the bag

Taking one challenge at a time and handling it with focus and energy.

Slappy Sacks

A game both similar and incredibly different to tummy sticks. The game is played between to males, who take turn slapping each other in the balls. The game finishes once a player taps out. The loser then must give the winner sloppy toppy

Sack Hat

A sack hat is a baseball cap that has the following characteristics:

-Being old
-A hat that old people frequently wear
-Having a really old or outdated logo

-Being a blank hat of any color without anything else on it
-The front of the hat being softer than the rest of the hat
-Having mesh on the back half of the hat
-Instead of velcro or being a fitted hat, it has little buttons that you have to click in place on the back of the hat
-Having a tag that says "one size fits most"

-Jerry has a Dallas Cowboys hat from 1991. It has soft foam at the front and little buttons at the back. It was probably worn when watching Troy Aikman play in the Super Bowl. It is a sack hat.

-Darius has a St. Louis Cardinals hat with a 1920's logo on it, the back half being mesh with little buttons. It is also a sack hat.
