fire-eating

The compound 'fire-eating' is a vivid example of a descriptive phrase that solidified into a fixed adjective. Its literal sense originates from the practices of street performers and sideshow entertainers who would pretend to ingest fire, a spectacle designed to demonstrate bravado and invulnerability. The term 'eat' in this context is used in an extended, almost metaphorical sense, meaning 'to take into the mouth' despite the dangerous nature of the object. This literal performance of fearlessness provided the perfect metaphorical foundation for the modern abstract meaning, which describes a person who is aggressively confrontational or eager for a fight, as if they possess the same reckless daring as the performer.
