I am probably not cleverer, but I usually call it the “after-credits scene”.
I would suggest that whatever term is used ought to have a variation to indicate a mid-credits scene – the one that usually comes after the initial bunch of credits (whatever you call that) but before the scrolling credits.
Never really had a name for it. Until The Avengers.
I have a small side gig reviewing movies and so my wife and I first saw The Avengers at a press/publicity screening about two weeks before it was released. I’d heard there was a post-credits scene and so we waited. And then nothing. Turns out it hadn’t been attached to the print at our screening.
So it opens and we starting hearing about the shawarma scene that we missed.
So now, at the end of any movie where we think it is possible we say some version of “do you think there’s shawarma?”
I don’t go to the theater for films as much as I used to. It used to be that as soon as the credits started or even when people thought the credits were about to start, they would bolt out of the auditorium like Olympic runners. (I always sat through the credits because I’m a movie nerd.) Has the proliferation of credit cookies lessened this behavior?
Lessened, yes, obliterated, no. And only for movies where the audience expects that there may be stingers. A serious drama will still have people rushing for the exits as soon as the lights come up.
Ray Bradbury had a short story titled The Anthem Sprinters. It had to do with people running for the exits after a film(in Dublin, Ireland) ended and before the national anthem started playing.
One of the most interesting examples was Wild Things. If you had walked out when the end credits started, you’d be missing a major portion of the movie. As the credits rolled, they began playing additional scenes that revealed major plot points.
I call it a stinger, because I’ve got www.mediastinger.com bookmarked on my phone. It’s a site that tells you if there’s a stinger or not, so you don’t wait through the credits pointlessly.
I remember the original Muppet Movie had Animal after the credits telling everyone “Bye bye!”.
But the funnier one was the guy waiting in the taxi at the end of Airplane!
