让我们一起数星星吧你这智商只配数月亮
[ràng wŏ men yī qĭ shù xīng xīng ba nĭ zhè zhì shāng zhĭ pèi shù yuè liàng]
Translating to 'Let's Count the Stars Together—With Your IQ, You Are Only Capable of Counting the Moon.' It is an ironic way of saying someone lacks intelligence, comparing the ability of counting stars (hard task) versus just counting moons (easier task), while seeming to invite friendly activity together at first glance.
