The term "raunchy" is an adjective that describes something as being sexually suggestive or vulgar. It can refer to anything from a person's behavior, clothing, music, or language that conveys a sense of sexuality in a bold and unrefined manner. The word has its roots in the 19th century term "raunchy" which means dirty or filthy, but over time it evolved to mean something more related to sexually suggestive behavior or content.
