"Callipygian."
The Venus Callipyge, also known as the Aphrodite Kallipygos or the Callipygian Venus, all literally meaning "Venus of the beautiful buttocks", oh absolutely, yes! Love it!
Cunnilingus is a fantastic word (insert your own "get your tongue round it" punchline).
Also love thundercunt, quintessential, whimsical, ridiculous, and eclectic.
