腰部主播 (yāobùzhǔbō): mid-tier streamer

Chinese e-commerce/MCN industry slices creators by body part metaphor: 头部 (tóubù) 'head' = top tier (massive followings), 腰部 (yāobù) 'waist' = mid-tier with solid audiences, 尾部 (wěibù) 'tail' = small creators. Brands often prefer 腰部主播 because their fees are reasonable and their audiences are still highly engaged.

Picture the influencer pyramid as a body: head at the top (megastars), waist in the middle (workhorses), tail at the bottom (long tail of small accounts).
