What does it mean when a sofa appears in a forum article sofa?

"Sofa" is the name given by some netizens on the forum to the position where the post was first replied to.

Some netizens really like to be able to grab this position, so wait for the new post to come out.

Generally, I don't look at the content of the post, and directly enter the word "sofa", "occupy a seat" (that is, the position of the first reply).

It's the bench. It means to occupy a seat.

After the landlord postes, the location of the first person to reply to you is called the sofa.
