What exactly is the reply?

How to answer depends on the specific context. If someone else is asking questions, just introduce them truthfully; If others are surprised, so be it. If you really don't know what to say, change the subject.

First of all, we must understand that the new word "ghost" is not a swearing word at all. In fact, it is an inquiry or surprise attitude towards the other party about the problem or the status quo. For those who don't know the details of the incident, the sentence "what the hell" represents more of an inquiry, with a meaning similar to "what do you mean" and "what's going on".

For some emergencies, the sentence "what the hell" is more of a sense of surprise, meaning "really!" Oh, my God.

There are many new words like ghost on the Internet. Let's take a look at them together.

"skr" I believe you mean the sound of tires rubbing against the ground, which later evolved into the first letter of a dead man's Chinese pinyin, meaning that this person is very powerful.
