What does “sigma” mean?
Sigma means a lone wolf who succeeds on his own terms, outside the usual pecking order. Among kids it has flattened into “cool,” often ironically: “what the sigma?”
Where it comes from
From the “sigma male” idea in online self-improvement circles, a supposed rank beside the alpha, spread in the early 2020s through edits of film characters set to music. By 2024 kids used it as a plain compliment or a joke. Google’s 2025 Year in Search listed it second among the slang people asked about.
Sigma in a sentence
- He fixed the printer without telling anyone. Sigma.
