The term **色狼 (sèláng)** is a compound word formed through metaphorical association: the character **色 (sè)**, which literally means "color" but is commonly used to denote "lust" or "lewdness," is combined with **狼 (láng)**, meaning "wolf." The wolf is a cultural archetype for a greedy, predatory, and threatening animal. By combining these concepts, the word creates a vivid metaphor for a person—typically a man—who preys upon others with aggressive and unwanted sexual advances, thus equating their behavior to the predatory nature of a wolf driven by base instinct.
