a chick with a hot body and a cute face who is unhealthy internally, whether by high cholesterol, genetic defect, addiction, infection, or other ailment, to the extent that her value as sexual partner is greatly diminished
"Remember that hot chick I brought home from the bar last week?"
"Yeah, you hit that?"
"I wanted to, but it got weird. She had some kind of brittle bone disease so she gave me all sorts of rules about what I could or could not do. Frankly, it was a complete turn-off."
1) Much like a butterface, except instead of liking all of her "but her face," he likes all of her except for everything about her. Hence, "but her her."
2) A girl that's so unattractive in every way, that a guy would not consider doing anything romantic with her, ever, because they don't yet have paper bags that cover the whole body.
(Ex 1) Guy: See that? I'm liking all of that butterher.
(Ex 2) Guy 1: There's this girl in my _____ class who is like the opposite of attractive.
Guy 2: Is she at least a butterface?
Guy 3: No man, I know the girl he's talking about, I wouldn't even get near that, she's more like a, a...
Guy 1: ...butterher.
Guy 2: Awwwwwww...
