I wasn't suggesting one meaning or another or that you didn't know.  I was merely trying to clarify because that term can have two meanings, and they are opposite.  That's why I wanted to be sure everyone had the same meaning in mind.   There are some real butterface and butter bodies out there...   The butter bodies usually show a face or partial face, but they're lying on their stomach or hiding 20 pounds of lard with a pillow.
