A lot of people are using is incorrectly in this thread. In this context it would generally mean a show about the show or shows in general. A very overt example would be The Larry Sanders show from back in the day. It’s a show about a show being made. More broadly it can be something kind of self referential like Community that heavily plays on expected tropes for sitcoms. OP is pretty heavily indicating a show like She Hulk which breaks the 4th wall but isn’t really meta until the end when the character speaks to the writer of the show.
