It's actually a new widespread name originating with The Mystery of Gravity Falls. It's basically the name he used for the video, not the episode. This is confusing everyone.

I told OnlyOnTuesdays88 about this and he's protected the page title "The Final Showdown" to prevent people from repeatedly creating it or moving the page Season 2, episode 18 to it.
