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."
Someone With both a ugly face and ugly body, more or less the combination of both a butterface (someone with an ugly face and an alright body) and scuffin muffin (someone with a cute face and ugly body).

Girl #1: That girl I hooked up with last night was super hot Girl #2: Ya right, she was a butterfaced-scuffin muffin
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."
