The word 走人 is formed by combining the character 走 (zǒu), meaning "to walk" or "to leave", with 人 (rén), meaning "person". It creates a vivid, almost literal image of a person walking away, which conceptually fuses into the idea of someone departing or being dismissed from a place or situation. This formation directly mirrors the action it describes, painting a miniature scene of a person in the act of leaving.
