A Colombian necktie (Spanish: corbata colombiana or corte corbata) was a form of post-mortem mutilation consisting of a deep incision under the victim's chin, through which the tongue is pulled out and left hanging down in grisly resemblance to a necktie.
This method of execution is one of the goriest. The victim's throat is slashed, often with a knife but really any sharp object would do, and then their tongue is pulled out through the open wound. During La Violencia, a Colombian period of history fraught with killing, this was the most common form of execution. It is used mainly to intimidate others who encounter the body after the fact.
