‘疯言疯语’ literally means ‘crazy speech, crazy words’—repeating the character 疯 (crazy, insane) emphasizes irrationality and loss of coherence. It refers to speech that is disjointed, illogical, or wildly exaggerated, often suggesting mental agitation, delusion, or extreme emotional distress. Unlike clinical terms, it’s colloquial and expressive, used more for vivid description than medical diagnosis.

This phrase carries a strong negative connotation and is typically applied to spoken utterances—not writing—and often implies the speaker is not in full control of their thoughts. It appears frequently in informal speech, literature, and media when depicting characters under stress, grief, or psychological strain. While it contains 疯 (which can relate to animals in other contexts), its core usage centers on human cognition and emotional states—not animal behavior—so its primary domain is Emotions.
