AMICICIDE — [Noun] The act of killing a friend. From Latin amicus ("friend") and -cide ("killing"). Unlike "fratricide" (which specifies the murder of kin) or "homicide" (which encompasses all human killing), amicicide is the betrayal of chosen bonds. It is the knife slipped between ribs by a hand that once clasped yours in laughter, the poison stirred into wine by the same fingers that poured celebratory toasts, the bullet fired from a gun held by someone who once swore to stand beside you—the ultimate perversion of trust, where love curdles into violence.
