index pointing at the viewer

It's a finger pointing directly at the other person. It's the most intuitive way to express "you."

It's fun to use playfully when chatting with friends. However, it can be rude to use with superiors, so use it with caution.

The meaning of this gesture varies greatly depending on the culture. While it's a common expression in Western cultures, it can be considered somewhat rude in Asian cultures.

In modern social media, it's frequently used in 'POV (Point of View)' content or to deliver direct messages. Especially among Gen Z, it has become a powerful communication tool to single out "you."
