the place where a girl rests her head when shes leaning against a boy. it is usually very comfy and is located just under the shoulder
Girl: i am oh so tired, if only i had a comfy place to lean/sleep on
Guy: oh, why don't you lean against my shoulder nook.
Guy: oh, why don't you lean against my shoulder nook.
