break the fourth wall
Of fiction, especially theater, film, or television, to break the illusion of separation between the audience and the fiction itself, either intentionally or unintentionally. Taken originally from theater, in which the fourth wall describes the invisible "wall" that stands between the audience and the stage. We were enjoying the play, but one of the actors kept breaking the fourth wall by glaring at the audience any time someone made any noise. I love shows that break the fourth wall—it makes me feel like I'm in on the joke.
the Fourth Estate
The people and organizations that report the news, or news journalism as a whole, regarded as having palpable but unofficial political influence. One must never forget the sway held by members of the Fourth Estate—if we want public support, then we need the press on our side.
fourth wall joke
In fiction, especially theater, film, or television, a joke that intentionally draws attention to the illusion of separation between the audience and the fiction itself. I love it when a TV show throws in a good fourth wall joke—I think it's fun being in on the humor like that.
fourth wall
The imaginary barrier separating performers in a TV show, film, or play from the audience. I hate those shows that break the fourth wall—I don't want to feel like the characters are having a conversation with me! Stay in character and don't break the fourth wall!
