What does sigma mean?

Short answer: Cool, independent, a lone wolf, usually as a joke.

Kids call someone "sigma" for doing something bold or not caring what others think, or say "what the sigma" instead of "what the hell." Much of the time, it's used ironically, to mock the very idea.

Where sigma comes from

"Sigma male" grew out of online writing about male hierarchies: alpha (the leader), beta (the follower), and sigma, a successful loner outside the hierarchy. According to Dictionary.com and MEL Magazine, the term was used from 2010 by far-right blogger Theodore Beale (Vox Day) and later in a self-help book. From 2021, "sigma" memes spread on TikTok and YouTube, often with clips of Patrick Bateman from the film American Psycho, and kids picked up the word from the memes.

Is sigma a bad word?

Short answer: It isn't a swear word, but its roots are in "manosphere" content.

The alpha-beta-sigma hierarchy comes from online communities that rank men by status and success with women; MEL Magazine describes the term's originator as holding racist and misogynist views. Most kids who say "sigma" are repeating a meme. MEL Magazine and Dictionary.com note that the term comes from content that ranks men by status, including with women.

The habit kids may copy: never show feelings

The "sigma" character in the memes is cold: no tears, no fear, no need for anyone. Kids who copy the character may start to hide their feelings.
