Easy virtue is a term that can be considered derogatory. It is often used to describe a person who is perceived to have a low moral character or lacking principles, particularly when it comes to sexual behavior. Synonyms for this term include promiscuity, licentiousness, and wantonness. These words all describe a lack of restraint and suggest that the person in question engages in immoral or sexually deviant behavior. Other synonyms include immorality, debauchery, and lechery. While these words may be more appropriate in certain contexts, they can also be seen as harsh and judgmental. It is important to use sensitive language when discussing sensitive topics such as sexuality and morality.
