What do you call this or is there even a name for it?

So, you know how some people write stories in more of a script style, bolding the names and italicizing the actions, for example:


Johnny: (cruelly) I never loved you.

It's not exactly a script, but it's not in traditional short story format either. So, is there a name for this format, or is there a name that's not official that maybe you use for this? Or is there a good name you can think of to start calling this??

If I said "dialogue panels" or "dialogue story," would you automatically know what I was talking about or not?

Thanks for your help.
