hacky sack

the most kick ass past time in the world. when participating u use a small bag filled with sand or beads. you can hit the hacky sack with anything on your body except from ur elbows to your hands. the object of the game is to keep it from hitting the ground and trying to get everyone who is playin to hit the hacky sack at least once. if someone misses a perfectly playable ball, they get stiched by the person who hit it to them. stiching is where you get the hacky sack thrown at you as hard as the last person to hit it to you can throw it. after you dominate the art of getting hacks you can go freestyle and you can try getting stalls (where the hacky sack stops somewhere on your body, other than from your elbows to your hands, and you resume play after however long you want to keep the stall), and other cool moves such as kicking the ball alot of times by yourself until someone yells at you and tells you to pass.

noah starts the hack and wont pass the hacky sack
Zach " Damn it noah, pass the sack"

Big Jon "i hit that ball perfectly to you and you missed. you know what that means"
cameron "DAMN IT!!! I hate stiches!!!"

Indian Hacky-Sack

When in a threesome, the act of a man's testicles slapping against the forehead of a third member located beneath the man's partner.

Roger: Gladys, why is your forehead so sweaty?
Gladys: Man, Frédéric just gave me Indian Hacky-Sack with Joanne. It was ball-slapping fun!
