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 male

A type of men who wanted to be a "alpha male" but wanted to be like cooler or some crap?
So they decided to make their own type of male.

Person 1 (a beta male): Yoooo, you're such a alpha.
Person 2 (an absolute sigma male): No, no, no! You absolute IDIOT! I am a SIGMA MALE, get it right you beta b*tch.

Sigma Male

An incredibly pretentious, smug person who believes they are somehow more unique and special than everyone else, and allegedly don't need to prove it to anyone (or so they claim).

They also unironically idolize the character, Patrick Bateman from American Psycho, treating him as the archetypal sigma male, when said character is actually a depraved psychopath, necrophile and serial killer who is not even supposed to be likable in the first place and was created by the author, Bret Easton Ellis, as a negative caricature of shallow, materialistic yuppies from the 80s. And no, almost none of these "Sigma" males have actually read American Psycho, nor seen its film adaptation, hence why they completely miss the point of his character and admire him for all the wrong reasons.
