Sigma

While it previously meant "an adult male who was particularly cool and followed the right way of life" (according to the ones who made up the word, that is), this word became nothing more than brainrot word filler. When spoken today, the word usually has no actual coherent meaning behind it (similiarly to the word skibidi, which is also a meaningless word). The only reason you would say this is either as a joke or because the word is catchy

...Also it's the 18th letter of the Greek Alphabet.

“Sigma”

A “sigma” person is a person who is usually racist, misogynistic and can’t stand the lgbt or furry community, usually by making fun and or generally bullying a member of a certain community, and then having others justify their actions by calling them a “sigma”, not to be confused with actual sigma individuals that actually have respect for peoples feelings.

(Not a rant post)

Person 1: “go kys furry, you probably touch animals”

Person 2: “bro you are so “sigma” !”

Sigma Hater

One who possesses a disproportionate disdain for single bonds. Known colloquially as "pi snobs," these individuals are predisposed to looking down on saturated molecules.
