A lady's ass that is so flat and wide that it resembles a tank like structure. If she layed down you can use that tank ass for a table.

Generally, a wide, thick butt that doesn't have reasonable curvature (A.K.A. bubble butt) or shapely definition.
A large butt that lacks roundness (may be flat in places), although it may have depth, and a shelf.

My girl gained a bit of weight after the baby, and it all went to her hips. Her booty used to be round, but now it's more of a tank ass now.

ass-tanking is when you put your index finger in your crack, just like you do at the gas station with gasoline gun. then, you keep it there until the finger is "ripe" and ready. after you smell it. the longer you tank, the more enjoyable it is.
