Get your ass in gear 

Thiis means to hurry the fuck up, and start moving your ass instead of sittin on it. Often told to lazy slackers sitting around on their fat asses smokin bowls and updating their face book accounts.

Tony : Eric why don't you get your ass in gear and get a fuckin job!

Eric :I will man,just let me finish burn'in one and update my facebook account.
