The completion of a full day's work.

Co-worker 1: "Hey , Niqua, you doing any overtime today?"
Co-worker 2: "No, not hardly! My sack is full. I'm finished for today."

Ball my Sack 

When one screws up a task and gets frustrated.

“Well ball my sack, I just totally messed that shit up.”

“Did you see that ECN that Travis Kyle just released? He really balled my sack.”

lick my sack 

Something Phil Anselmo shouted on Pantera's 1990 album, "Cowboys from Hell."

My stand is the human race
Without a label or a face
So they can lick my sack - "Hesresy," Pantera

Pulling a MyBack

When you purposely ignore someone for the fun of it, and then pretend to get mad at them for cluttering up the chat room because they tried to reach you for a period of time. (this is via internet chat/ or texting)

This is named after a Gamer who's name was "MyBack" and would do this in group chat.

Man one: Hello! 9:30
Man one: Hello? 9:35
Man one: r u there? 9: 53
Man one: Plz answer! 10:00
Man one: It's important! 10:15
Man one: r u listening to me? 10:23
Man one: dude (or chick) PLEASE PICK UP IT'S IMPORTANT 10:43
Man one: ok ill see you later.... 10:54
Man two: SHUT UP 10:54 (one second later)
Man one: dude u r srsly pulling a myback

Stealing a friend's song on MySpace.

I had this really awesome song on my page, which I loved until Karen myjacked it. Now no one will know which one of us found it first. What a douche!
