So, you know how sometimes grown-ups get awards for being really good at acting in movies or TV shows? Like, they get trophies and stuff?
Well, there's another kind of award that some grown-ups get, but it's not for being really good at acting. It's actually for being really bad at it... like, so bad that people watching the movie or show just cringe and feel uncomfortable.
That award is called the Golden Raspberry Award, and they give it to actors who did a really bad job in a supporting role (which means they were one of the less important characters in the story).
It's kind of like a joke award, because they don't really want to be mean to the actors or hurt their feelings. But sometimes, when an actor does a really, really bad job, it's hard not to notice, and that's when they might get a Golden Raspberry Award.
So, if you ever hear someone talking about the Golden Raspberry Award for Worst Supporting Actor, it just means they're talking about a grown-up who did a really bad job acting in a movie or TV show, but it's okay because it's just for fun!
