sigma

In contemporary internet subculture, a "sigma" refers to a man who is perceived as highly successful, self-reliant, and independent, often operating outside traditional social hierarchies. The mental image is that of a "lone wolf"—someone who doesn't need to conform to group dynamics to validate their worth or power. While initially used in the "alpha/beta" hierarchy context, the term has evolved into a meme. It is often used ironically to describe someone acting stoic or detached, but can also be used seriously by those who admire a masculine ideal of solitary, quiet ambition.
