Is this expression out of style? You know; like "right on."?

Pretty much

I still hear it. I don’t think it’s a saying that was ever overly in so it’s not overly out.

Among the youth maybe but generally it is still widely used!

I say, “he doesn’t have a scooby” or, ‘he doesn’t have the foggiest”

It’s an expression I use because it is self explanatory. To my mind it is neither “in” or “out” of style.

Not at all. I use it.

Sounds OK to me, but I’m old.

I don’t have a clue about what you mean.

Please tell me that ‘on accident’ is on the way out (and I’m BEGGING you, here).

@RadioFlyer “on accident”???

Yes. For some reason in recent years, MANY younger people say that something happened “on accident”, for some reason finding that ‘by accident’ just wouldn’t do anymore….

@RadioFlyer “on accident” sounds absolutely ridiculous! Who are these people? I’ve never heard it said here (NZ), I’m very pleased to say.

Well, mate, all I can say is….be ready.

During the past five years or so, I’ve heard it countless times as people walk down the hall at work, or while passing them in a grocery store, and in other places.

You are right….it does sound ridiculous, or to put it another way…..pretty damn stupid. But there you have it….
