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.

The expression of which your ass is grass comes from if you hear this you better get out of town because you're likely to get shot hung or end up with your head on a stick
