Usually used when derogatorily referring to females.
In some tribes of Sierra Leone, "A woman who is a Paramount Chief may have sexual intercourse with as many men as she pleases."
Being slutty is common in certain animal species; it's social acceptance varies from culture, geographical area to time period.
