Let's understand sigma slang meaning to describe women. Although the word "sigma" is most frequently used to refer to men, some people have begun to use it to refer to women who are just as autonomous, self-sufficient, and disinterested in conforming to conventional societal norms. A Sigma woman may resist peer pressure or groupthink, stay emotionally in check, and concentrate on her objectives. The term is still developing, though, and women are less likely than men to use it. However, in some situations, the Sigma attributes can be applied to people of any gender.
