What does it mean when someone snaps their teeth in a chat?

In the chat, someone sent the "Pig Teeth" emoticon package to express funny, happy, and joyful meanings.

The original meaning of "Pi Ya" is to grin and show teeth, which comes from the first chapter of the second part of "Song of Youth" by modern writer Yang Mo: "He turned his big head and looked at Jiang Hua with bared teeth. ”

After that, “Pit teeth” first appeared as an emoticon in QQ, used to express happiness and smile with open mouth and exposed teeth. Later, this series of emoticon packages appeared again in WeChat and became the number of uses. One of the top memes.

Extended information:

From the perspective of the entire emoticon package as a whole, the Pi Ya expression only has three elements.

The eyes, mouth and a circle as the face are such a simple image creation. The eyes that squint like the moon and the smile that knows how to grin and show teeth can make people clearly feel the friendliness expressed by this expression. This is also an important point that is different from the "smile" in the same series of emoticons.

From the perspective of the entire emoticon package as a whole, the smile expression also has the same three elements.

The eyes, mouth and a circle as the face are such a simple image creation. The problem lies in its eyes, and the main performance lies in the direct vision of the eyes. The same look as sadness or goodbye makes people look like a fake smile, so the smile looks much more negative.
