Quimm refers to the most precious part of the female anatomy. Quimm can be considered the vagina but more frequently may be an alternate word for the Fillet, Lips, or Labia. It should also be noted that the Quimm being discussed would be attractive and pleasing not only to the sight but also the touch, smell and taste. NOT some ugly, misshapen, smelly, ratty old thing.
"She was taking it the ass like a true porn star when I noticed her luscious quivering quimm."
