The origin of the word vest on the internet

In Chinese mainland, the word vest may come from a joke, which is as follows:

A tiger chased a snake and the snake fell into the river. Soon a turtle came out. The tiger grabbed the turtle and said, don't think I don't know you when I put on my vest!

In this joke, the tiger regards the tortoise as a snake wearing a vest, and the vest becomes an alias. In 2000 CCTV Spring Festival Evening, Zhao Benshan's sketch "The Hour Worker" used this joke. Since then, this joke has spread more widely, which is probably the origin of this network term.

Another way of saying it is that the word vest comes from the red vest worn by traders in the stock exchange. Because most traders serve other major shareholders, that is, they are trading puppets of shareholders, vest was later used to describe the ID of the avatar on the forum.
