long white legs and supple, callipygous ass

He enjoyed Nurse Sue Ann Duckett's long white legs and supple, callipygous ass; he often neglected to remember that she was quite slim and fragile from the waist up and hurt her unintentionally in moments of passion when he hugged her too roughly.
-- Catch-22 by Joseph Heller

I finished reading Catch-22 in Malaysia (and left it with starbytes) and made some notes for posts on this here book blog upon my return. I didn't know what callipygous meant when I read it, and finally looked it up just now. While I hope to say and write callipygous regularly from here on out, reality will likely see me use it a few times and then never again. If you say it or write it to me, I will go weak at the knees.
