Sigma

Used to be a letter from the Greek alphabet and a math term but now it is being used by brainrotted gen alpha kids to make themselves cool in expectations, but in reality they are legit making an ass of themselves.

Guy: Sorry, we're just friends Emma...

Emma: It's ok, let's stay friends then!

Gen Alpha kid: OMG HE REJECTED HER, HE'S SO SIGMA AND MISOGYNISTIC 🥶🥶🥶

Guy: Uhhh... (Oh my God child.. SHUT THE FUCK UP)

Sigma

A very sexy ass looking person who has success in all areas in life. He knows how to handle business inside and outside of the bedroom. Sigma is above an alpha. Sigma’s are fucking badass and their level of masculinity is as high as it can goes.

“My boyfriend is such a sigma.”
“Damn, he smells good and looks good and is very masculine, what a sigma.”
