assterpiece 

The amalgamation of "masterpiece" and "ass" - essentially a masterful ass. This is applicable to any female that has a lot to bare with her derrière.

Jessica Biel has an ass that won't stop! What an assterpiece!

Even in her older state, J Lo still has a mighty fine assterpiece protecting her backside.
