The word 骗局 is formed by combining two characters: 骗, which means "to deceive" or "swindle", and 局, which originally means a "game" or "situation" but here implies a "setup" or "scheme". Together, they create a vivid conceptual image where the act of deception (骗) is framed as an entire orchestrated scenario or trap (局), effectively conveying the idea of a carefully constructed fraud or hoax designed to ensnare someone.
