A hangman's noose. Phrased as such to imply formality and common occurence in the region of Mississippi and other deep southern states, of the event of a hanging, not necessarily of a specific race or group of people, but anyone unfortunate enough to piss off a redneck. Used in reference to a hanging to make light of, or lessen the horrific nature of it.
Ex.1.: "Hey boy, you better get on outta here before you find yourself wearin' a Mississippi Necktie."

Ex.2.: "Billy Bob wore a Mississippi Necktie to his weddin'."
