So, imagine a bunch of horizontal scars along the neck with teeth growing out of them, like a bunch of little mouths in her throat. Her neck is shredded enough that the muscle can't properly support the weight of her head anymore, hence the "accordion" metaphor. It's hard to describe it with nothing but words and I ended up fighting the character limit lol.

So... think, an extended accordion with the head of a wolf leaning to one side, and in the folds of the accordion, there are teeth...

The words "meat accordion" have come to mind, and I'm not enjoying the mental image.
