The word 胡闹 is formed by combining two vivid conceptual images: 胡, which historically evoked the stereotypical "wild barbarians" of the northern frontiers, carrying a sense of something irrational, foreign, and unrestrained, with 闹, which paints a picture of noisy commotion, disturbance, and unruly action. Together, they fuse the idea of "barbarian-like chaos" or "irrational disturbance", creating a single term that captures the essence of acting wildly, foolishly, or making a senseless fuss.
