Neutral face

This emoji is fairly popular, but is used more often by younger generations. It is most commonly used on social media platforms such as Instagram, Facebook, and Twitter. It is not considered a rude emoji, but is instead used to express a lack of emotion or enthusiasm.

The history of this emoji dates back to the late 1990s, when it was first used in the Japanese mobile phone messaging service, i-mode. It was then adopted by other messaging services, such as SoftBank, and eventually made its way to the Unicode Standard in 2010. Since then, it has become a popular emoji used across many different platforms.
