A high-school sub-genera of people who are always in the corner or off to the side playing hackey-sack. They are really into their game trying to keep the hackey-sack going and will not let anyone else play except their fellow sackers. Alot of times they will wear Ear Flap Hats and have renaissance type shoes and backpacks.
Kid,"Hey can play hackey-sack?"
Sacker,"No get out of here!"
