Your ass is grass 

Your precious buttocks has now become the center of a very farcical taunt. This phrase implies that "you are going down" in the near future. This phrase being said to you means that your inevitable fate is nearing. It is only half of the full sentence "your ass is grass and i'm gonna mow it." Basically someone is threatening you and you better get the hell outta dodge.

"You fucked my wife enough times Todd, your ass is grass!"

get your head out of your ass

If someone tells you to "Get your head out of your ass," it means that you have to start paying more attention to what's going on around you. It could also mean that you have to stop being so consumed with yourself, and your own well being, stop being so conceited.
