The word "black-bone mackerel" is actually a homophony of "wujisubaoyu". This is a curse word, and it seems unsightly to say it directly, so many people will use the homophone "wujibayu" instead, that is To feel speechless about something.

The rice circle term "black-bone chicken and mackerel" is another homophonic meme after the abbreviation. They are also very interesting memes. Many people thought that this meme used to mean something black, because black-bone chicken and Spanish mackerel are quite black, and some people always thought it was a Korean transliteration. In fact, this word Bin does not just mean the literal meaning. This word means that I am very speechless about some behaviors and do not know how to comment.

The terminology used in fan circles is just like Chinese culture, which is broad and profound. Many seemingly simple sentences do not mean what they literally mean, or what you subconsciously understand, and there must be many hidden meanings in them.
