Grown Ass: (Adjective) Referring to the maturity or age of a person.

Look who it is, everybody: Dakota Fanning, all growns up! It looks like she's turning out to be quite the lovely and sophisticated looking young woman. And what a breath of fresh air this is, too, after my day-to-day dealings with the products of the Disney Skank Factory. It damn near makes me cling to hope for the future of the entertainment industry.
