The first time I saw “sigma” used as slang, it was in a random comment under a viral video. Someone wrote, “bro just went full sigma.” I paused. Sigma? I knew it as a math symbol and a Greek letter, not something people say online.
Then I started noticing it everywhere TikTok captions, gaming chats, Instagram comments, even memes. Everyone seemed to get it except me. If you’ve ever felt that same confusion while scrolling or texting, you’re not alone. Let’s break it down in the simplest way possible.
