This is something a sacred person has created, and if someone says it, they die instantaneously. Only the person who created it can say it, unless given permission, but the permission only lasts as long as the person says. If someone that has permission or the sacred person, says it to you, you die.
Person: I will kill you!
Sacred person: Poturtle Yeet!
Person: Oof, I'm dead now.
