Noun - an offensive word used to decribe someone who is so utterly obnoxious no other word or phrase can accurately paint a mental picture of this person's personality...or lack of it.
A "Cunt" is an obsolete word for a side pouch that was once warn by farmers making hay bails. An implement called a Prick was kept in the Cunt and was used to prick and capture the twine from one side of the hay bail to the other. Later uses of the words Prick and Cunt have now become deflationary remarks. Cunt is not a swear word, once you know its real definition.
