Sigma expression

The "Sigma Expression" originates from the "Sigma Male" image in internet subculture—an independent, composed, and non-conformist male personality archetype. This expression is typically characterized by:

Naturally arched eyebrows forming a figure-eight shape
Slightly puckered lips, as if exhaling or lightly smiling
Relaxed facial muscles, with a disdainful or confident demeanor

It is commonly seen in meme videos and short video character performances, featuring strong stylization and emotional expression traits.
