233

233 is a popular cyber language which is the meaning of laughing. When you meet some interesting person, you can use this to show your happy mood.

The word first came from the Mop.com(a famous Bulletin board system). The founder of the Mop introduced some dynamic icons based on the Japanese language as the emoji of the website, which they numbered from 001 to 999, with a total of 999. The number 233rd corresponds to the emoji of a laugh, so in the process of continuous use, the Internet users in the website often directly type in the number of digital "233" to refer to the expression of the laugh. The word, therefore, became popular.

As the word got widely used, there are some related uses, such as when you meet some funny people, this degree of fun is extraordinary deep then you repeat the "3" of after the "233", like "23333" "2333333333333333333333", to increase the degree of laughing.
