亲爱的我们一起数星星吧你智商太低还是数月亮吧
[qīn ài de wŏ men yī qĭ shù xīng xīng ba nĭ zhì shāng tài dī hái shì shù yuè liàng ba]
A lighthearted and somewhat teasing nickname. 'Darling, let’s count stars together, but maybe we should stick to the moon because your IQ is too low.' The latter part could just be a joke showing playful banter between partners or friends.
