What is Message?

I keep seeing people on the live chats refer to Message as a means of keeping in touch.
But I'm not sure what it is. Is it it a particular app or site? It's hard to google it effectively because it has such a generic name.

If anyone can tell me and possibly link me to it, that would be great.

 

Message is a downcat. This is an in-house downcat and available nowhere else.

 

I don't know what Downcat is. Can you direct me where I need to go to use it?

 

I think Downcat may be like that Yoga position Downward dog!

 

I'm still not sure where to go to utilize it.

 

You'd utilize it while snipe hunting.

 

I hear snipes like chocolate, so bring some of that with you on the hunt.

 

Did you ever get an answer or find out later?

 

It's a replacement word for various spam content.

 

Can you give me an example?

 

No

 

I think I get it. If someone says add me on “app name” it shows up as the word “message” in chat
