Definitions
A 'sacrificial dummy' refers to an object, figure, or person used as a stand-in to absorb harm, damage, or negative consequences in place of someone or something more valuable. It is often used in testing, training, or as a metaphor for someone who is deliberately put in a vulnerable position for the benefit or protection of others.
