What Does Sigma Mean?
In modern slang, “Sigma” is short for “Sigma male” — a term that became popular in internet culture to describe someone who:
Works alone
Doesn’t follow group rules
Is confident but quiet
Seems “above” social expectations
Example in 2025 usage:
“He didn’t argue — just walked away and did his own thing. Total sigma move.”
The word is often used jokingly or ironically in memes or videos, especially on TikTok, YouTube, or Reddit. In serious conversations, it can sound immature or overly internet-based.
✅ Use it for fun or humor
Avoid it in professional settings
Where Did Sigma Slang Come From?
“Sigma male” came from the Greek letter ranking system (Alpha, Beta, Sigma, etc.) used in pop-psychology and internet personality content.
It originally referred to men who are successful but non-dominant, independent thinkers, or “lone wolves.” Over time, the term became overused online, and now it’s often used with sarcasm.
