The technical definition of the opposite of butterface: a member of the more feminine sex who's face is more attractive than her body.
Guy A: "You know that girl Lindsay Lohan? Dude, she is the only girl to ever transfer left to right along the Butterface-Scuffin Muffin Spectrum (B-SMS)."
Guy B: "In what way?"
Guy A: "Well her body was really smoking, and her face wasn't that great in comparison, but when she did drugs, she went all emaciated sudanese on us and her face never looked better by comparison."

The spectrum by which a girl's body is rated in comparison to her face, where butterface is an ugly face v a nice body and scuffin muffin is a nice face v an ugly body. A zero is optimal, denoting your body and face are roughly at the same attractiveness level.
Guy: "Ehh I'll give her a overall 7.5 on the hotness scale, but on the Butterface-Scuffin Muffin Spectrum (B-SMS) she's moderately leaning towards Scuffin Muffin."
