Chinese sex words, obscene language, curses and slang
Description from the site:
a number of useful words and cool expressions in the Chinese language (mainly Mandarin, plus some Cantonese specialties), some of which are rarely included in politically correct study books or censored student dictionaries. The reader is supposed to have a basic understanding of Mandarin and certain knowledge of the Chinese culture. Some of these words and expressions should be used with the greatest care, and people who do not know any Chinese at all should not use them unarmed.
