Some people think it has something to do with the English "second floor". Later, some lazy people wrote SF directly and spread it to China, which means sofa.
So some people think that "the first person to reply (second floor)" is the sofa. Therefore, there are also common words in the forum, such as "grabbing the sofa (meaning grabbing the position of the first reply)".
Social positive effects of online buzzwords such as "sofa";
1, ease the group mood. Network buzzwords are often triggered by a certain network term, thus intensifying the hidden social emotions of the public, making them explicit and expressing them through cyberspace.
This kind of emotional expression weakens the suppression and negative effect of emotion itself on individuals to a certain extent, thus alleviating the irrational impulse behind social emotions and avoiding larger-scale collective confrontation.
2. Reflect the group consciousness. Group consciousness often dominates the social perspective established among individuals within the group. Facing the complexity and concealment of social groups, it is an essential step to grasp group consciousness in order to realize coordination and effective guidance and management among groups.
