In today's era of social media development, new features emerge in tandem. One standout feature in this modern world is the emoticon, particularly XD. So, what is XD, and how does it become so popular? Join us as we explore below.

Defining XD
XD is the symbol for the icon (emoticon) depicting a smiling face with both eyes closed tightly.
X: Represents two eyes.
D: Represents a wide-open laughing mouth.
This is an icon with a delightful, crisp smile.
The emoticon XD, symbolizing emotional expression, is incredibly popular on social media platforms like Facebook, Yahoo, Zalo, etc. It is used to enhance your chat conversations and express your emotions in the moment.

When is the ideal time to use XD?
Fundamentally, people often resort to XD emoticons during cheerful, relaxed conversations, or when they wish to replace a punctuation mark with a playful touch.
Occasionally, use XD when you want to express emotions without explicitly saying anything or when there is hesitation. At such times, XD serves as a verbal substitute.

XD is frequently used in communication among young individuals in their teen years. Recently, the XD emoticon has made appearances in TV shows like 'South Park,' portraying an attitude of uncertainty or lack of clarity about something.
