A boy on QQ told me about wearing a vest. What does this vest mean?

Vest, this is an online vocabulary! It is the consistency of the name logo, which proves that you and he are a pair!

For example, the name of the group is "Do you still remember me", so the vest of the boy is: Forget you, the vest of the girl is to forget me!

This is a correspondence! Paired with you!

In addition, if you are a group, then the previous identification mark is also a vest, mainly to distinguish what kind of person you are!

You see, in YY, if you powder an anchor, then you can change it into his vest in the live broadcast room, which may be a pass for the future!

I think the boy you mentioned above likes you, so he confessed to you implicitly. If you agree, it's a formal confession! Maybe he is afraid of your refusal, so he is a little reserved!

I hope my answer is helpful to you!
