Obscenity refers to an offensive word, expression, or action. The term is usually used to describe a word or phrase that is offensive. It can be used to refer to behavior or other obscene actions. The term might be interchanged with lewdness, indecency, or crudeness.
Common obscenities include profanity or other so-called crude phrases. Things like pornography, especially when shown in public, are considered to be obscene. Public nudity would also be included as being obscene in some countries. What does and does not constitute an obscenity may vary slightly from individual to individual (and the society in which they live) based on what they believe to be inappropriate or obscene.
