“Necklacing is the practice of summary execution and torture carried out by forcing a rubber tire, filled with gasoline, around a victim’s chest and arms, and setting it on fire. The victim may take up to 20 minutes to die, suffering severe burns in the process.”
...The practice appears to have begun in the Cape area of South Africa in the mid-1980s.”

Africa has many, many wonderful inventions...
You do NOT want to see the images that come up on a Yahoo search for “necklacing”. Unreal, and sickening, to say the least.
