Promiscuity Definition from Encyclopedia Dictionaries & Glossaries
Promiscuity is the practice of having casual sex frequently with different partners or being indiscriminate in the choice of sexual partners. The term can carry a moral judgement if viewed in the context of a mainstream social ideal for sexual activity to occur only within exclusive committed relationships. A common example of behavior viewed as promiscuous within the social ideals of many cultures is a one-night stand and (as seen in this 2014 survey) is often the way researchers define a society's promiscuity levels at any given time.
