Why is the first reply called "sofa", the second called "bench" and the third called "floor"?

At present, there are generally the following kinds of analysis:

1, the word sofa comes from the BBS of a website. Someone posted a picture, and the person who replied felt good, so they used the word sofa as encouragement. Later, many noble-minded people didn't understand the word sofa, and then thought that sofa meant the first person to answer. Nowadays, many people say that they are sitting on the sofa for the first time.

2. I also saw an explanation: "A group of people were reading posts, and suddenly a new post was posted. The first reply lamented: sofa, and then all the new resources were lamented ... sofa is the homonym of sofa, which was later passed down. "

In the forum, there are usually many people attending. The landlord sends a main post indicating the theme of the forum, and then invites friends to come in and talk. Host-The landlord will have all the guests in the guest house, and of course there will be sofas and benches at home to entertain the guests, but there are too many guests, so all the guests should be treated equally, so the first one to arrive (the first one to reply) can only take the sofa, and the second one can only take the sofa.

4. The first reply post is generally considered to be the fastest, but some people, in fact, most people don't seriously read the main post at all, just to grab the first "supporter -top", so they are called "sofa". But more and more friends really think that the first reply is "sofa", so they quickly sit down or lie down, and then slowly appreciate the content of the main post.

The first person who answers is generally called the starter. When you talk, you say it's a sofa.

Another explanation is that the second floor refers to the second floor of the forum reply, which is homophonic "sofa"

Sofa should come from mop. mop forum has a function: you can view your own posts. So sometimes people see some very long and interesting posts, or posts with "potential" (there will be very long and interesting replies, but there are few replies now), and it is easy to find this again in the future (mop had a very heavy traffic at that time, only one page, and by default it showed that there was a reply within the current 30 minutes). So it's hard to find old posts. Of course, you always have to say something when posting. At first, it means "posting marks". Later, when I meet a long post (the first post is very long, or I reply to many long posts, such as a quarrel post), I say "move a sofa and watch slowly" or "move a sofa and sit and watch a play".

At that time, the wave of "grabbing buildings" happened in mop. At first, it was to rob a hundred floors and so on. When robbing a building, you can also use the words "move a sofa" to rob a building because you also need to say anything casually. Later, there was a trend of "grabbing 1 building", that is, the first reply (mainly because mop's page would not be refreshed at that time, so unless you refresh it manually, you will not see a new post immediately, so grabbing the first reply will be considered as "good luck"). If you talk too much when robbing a building, the building will be robbed by others, so you often only use the words 1 and 2 to rob the building 1, so that the words "moving a sofa" will be abbreviated as "sofa" or even "SF" (the initials of sofa). The act of grabbing the first floor is called "I am sitting on the sofa" or "sitting on the sofa" for short.
