Call me crazy, but Grady is an underrated sigma, he does so well in his classes and with the ladies, but gets almost no recognition for it.

A tri-sigma is a woman of class and stature. She is the girl next door. She is a little bit of everything; a trendsetter, an artist, and an athlete. She is classy, honest, chill, and respectable. She is the definition of sexy. A tri-sigma is who everyone wants to be. A tri-sigma girl is always on top.

The introverted alpha male. They do not conform to society standards and rather think for themselves. Sigmas have many traits often correlated with an alpha male. Although they can appear quiet to those who do not know them, they are actually outgoing once you speak to them. These people are on a similar hierarchy to an alpha male, although they are simply less extroverted and are more in tune with themselves.
Person 1: He’s quiet for an alpha male

Person 2: I think a sigma male is a better term

A word used to describe the kids who comment on phonk videos or Patrick Bateman Sigma short videos with the 🗿 Emoji. They spend their time in the youtube shorts section trying to find other 'sigma males' that are probally 10 year olds reaking their parents bedroom or either commenting 'women🍷' on every post they see.
Bro I was just trying to listen to some phonk but when I opened up the comments all i saw was the Sigma Kid.
