掐指一算此奶大胸之罩
[qiā zhĭ yī suàn cĭ năi dà xiōng zhī zhào]
This nickname, literally translating to 'With one count on fingers, here comes the best support for big chests', appears quite playful. Likely referencing supportive items like bras, but also humorously hints at fortune-telling culture in Chinese society.
