Meaning:

    “脑” means “brains,” “好” means “good,” “望” means to “hope,” and “有” means to “have.” This four-character term, coined by Chinese netizens in the form of a traditional Chinese idiom, can be translated as “brains are good things to have, and I hope you have them.” Obviously this is a harsh and joking way to call someone stupid.

    Example:

    A: 小明向我借钱，你说我借不借呢？

    Xiǎomíng xiàng wǒ jièqián, nǐ shuō wǒ jièbujiè ne?

    Xiaoming asked me to loan him some money. Shall I say yes?

    B: 脑好望有。

    Nǎohǎo wàngyǒu。

    Are you stupid?

    A: 什么意思？

    Shénme yìsī?

    Why?

    B: 小明喜欢赌博，你又不是不知道，还问我。

    Xiǎomíng xǐhuan dǔbó, nǐ yòu bùshì bù zhīdào, hái wèn wǒ。

    Xiaoming likes to gamble. You know that already, why do you have to ask?
