狂吼 literally combines 狂 (kuáng, 'wild', 'frenzied') and 吼 (hǒu, 'to roar' or 'to bellow'), resulting in a vivid verb meaning 'to bellow wildly' or 'to scream uncontrollably'. It conveys intense, unrestrained vocal expression—often associated with raw emotion like rage, terror, or overwhelming excitement. Unlike ordinary shouting (喊), 狂吼 implies loss of control, physical force, and emotional extremity.

This word is frequently used to describe animal sounds—especially large mammals like lions, bears, or wolves—but also applies to humans in heightened emotional states: a protestor screaming in defiance, a fan roaring at a concert, or someone yelling in panic. It carries strong imagery and dramatic weight, making it common in literature, film scripts, and expressive speech—not everyday conversation. The compound functions as a single verb and does not take aspectual particles (e.g., *了, 过) without careful context, as it already implies intensity and completion.
