SIGMA

In slang, the term "sigma" is often used to describe a person, usually a man, who is self-reliant, confident, and capable of thriving independently of social structures or hierarchies. It is derived from the concept of the "sigma male," which contrasts with the traditional "alpha male" archetype. While an alpha male is seen as a dominant leader within a social group, a sigma male is perceived as someone who prefers to operate outside conventional social dynamics and does not seek validation from others.

Sigma is a letter in the Greek alphabet. In this context, it is being used as a slang term. Slang is a type of informal language consisting of words and expressions that are not considered standard in the speaker's dialect or language. Slang words and phrases often originate in subcultures or specific social groups and can become widely used across different groups over time.
