You're probably making a joke, but I'll explain it just in case anyway. It's Prequel Trilogy (movies 1-3), Original Trilogy (movies 4-6), Sequel Trilogy (movies 7-9), and Expanded Universe (books, TV shows, comics, games, etc), fairly established terms within the Star Wars fandom.
As a bonus, there's also "Legends", referring to the EU content Disney decanonized when they started the sequels.
