obscene

Definition from Nolo’s Plain-English Law Dictionary

A description of material that the average person, applying contemporary standards in their community, would find appeals to the prurient interest in sex, with no legitimate artistic, literary, or scientific purpose or value. Pictures, writings, films, or public acts that are obscene under this standard (from the U.S. Supreme Court) are not entitled to First Amendment protection as free speech, and may be regulated or even criminalized.
