adj. a word describing the delicious character of a person's buttocks, based on its appearance and/or feel. It may also be seen as a play on words with the "butter" portion of the word.

Etymology: conjoined from the slang "butt", (shortened from "buttocks" meaning 'the two fleshy parts of the body posterior to the hip joints'), and "terrific" (meaning 'exceptionally good of its kind, or particularly excellent')

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.
