脏话比谎话干净一千倍
[zàng huà bĭ huăng huà gān jìng yī qiān bèi]
In the opinion of some internet users, dirty words ('脏话') are much purer and truer expressions comparing to lies('谎话'), because although they might seem vulgar, they express true inner thoughts without hiding any intent. This name might come from one’s dissatisfaction towards lying or dishonesty and prefers openness even if it seems uncouth.
