Heh-heh! Perhaps the strangest thing about "callipygian" (I doubt that more than 1 English speaker in 10,000 could define it) is that there isn't a more ordinary word for such a useful concept!

P.S. There's a related and equally rare word "steatopygian" (с жирными/толстыми ягодицами) -- presumably Sir Mix-A-Lot would argue that the two words are synonyms, but not everyone would agree...
