I take it that it means, "Good story, and I think you made it all up."

Am I right?

6. I first got a "Cool story, bro" reply a couple of years ago on a social website that

no longer exists, where I used to post stories & articles.

I hadn't seen it before, so I didn't think much of it at the time; however, I later saw that the guy was replying "Cool story, bro" to every single story he replied to.

7. I had taken it to mean

that the story is boring and not worthy of more comment than that
