What does cold salad mean?

A joke! New words bred in modern society! The specific meaning is that he doesn't know, his attitude in answering your questions is very bad, or he doesn't know what to do at all, which is obviously perfunctory! However, the word cold salad is derived and has the meaning of low-key treatment! If someone says that again in the future, you can ignore it. Just kidding, there is no other bad meaning! Of course, if someone asks you what to do, you can also say so, but I don't want you to say so irresponsibly! You still have to help if you can help, right?
