Codburger
Inspiration: A meat cutting industry was packaging ground beef when a customer had called asking the price of Cod Fish. After looking up the price of the Cod Fish, the wrapper had continued to package the ground beef without changing the name of the price tags. Thus labelling all ground beef as "Cod Filets"; which sparked the term "Codburger".

Definition: Untrimmed and unwashed vagina -- used so much to a point where nobody would wish to touch it.
She seemed to be a MILF until I saw her Codburger.
