3D Ass This differs from a 2D ass in that it has dimensions of height, width and depth when viewed from all angles.
4D Ass spans all dimensions of height, width, depth and time. You will watch a 4D ass ALL DAY LONG.
Response: Yep, 2D. Too flat. I saw a 3D ass a few minutes ago, but I'm still dreaming of the 4D ass I saw on the Grammy Awards when Beyonce was performing. I so glad I Tivo'd it.
