Black Mirror may have just released its fourth season, but it turns out lots of fans are just realizing what the show's title means.

If you didn't already know, the title of Black Mirror is referring to the reflective black screen when your phone or computer is out of use.

The show's creator, Charlie Brooker, confirmed the meaning behind the title to The Guardian back in 2014. He said, "any TV, any LCD, any iPhone, any iPad—something like that—if you just stare at it, it looks like a black mirror, and there's something cold and horrifying about that, and it was such a fitting title for the show."

Taking to Twitter, fans shared reaction gifs of the moment they figured it out. Check out our favorites below.
