It is often said online in posts what sofa means

The first person to follow the post is called "sitting on the couch".

It is said that the word sofa first appeared in an adult forum, basically the origin of the sofa is: someone posted a picture of a beautiful woman, and the person who replied to the post said that it was good to be punctual, and he wanted to sit on the sofaXXX. Then, all those who sent good pictures and got support said to sit on the sofa.

Later, many high-minded people didn't understand the word sofa and then thought that the sofa referred to the person who was the first to reply to the post, and now many people say that the first reply is the sofa, really. Go to the sofa when you read an anti-Japanese post, and sit on the sofa when you read a political post, you are really energetic. Hats off to so many people who are always on the couch!

Truth be told, this explanation makes a lot of sense. It can also be verified, in the past, there were several adult forums on the Internet, which were more popular, and there were more people living there, and there were more words.

But I also saw an explanation that was: "A group of people are looking at the post, and suddenly a very new resource comes out, and the first one to reply to the post sighs: so fast, and then all the new resources have people go up to sigh so fast...

The sofa is a homonym for so fast, and then it has been handed down. ”

The homonym of the first release.

The homonym of so fast.
