There is a wide range of synonyms to denote the term "obscene literature" that refers to written or visual contents that are sexually explicit, offensive, or indecent. Some of the synonyms include pornographic literature, erotic literature, salacious literature, smut, lewd literature, dirty books, adult literature, licentious literature, and more. Such contents are often viewed as unsuitable for mainstream audiences due to their explicit or vulgar nature. Many countries have laws in place to restrict the dissemination of such literature and the censorship of these materials continue to be a topic of debate among lawmakers and society as a whole. While some argue for freedom of expression, others call for stronger laws to regulate the publication and distribution of obscene literature.
