As mentioned in The Oldest Ones in the Book, those tropes cannot be any more recent than 1980, and even then, that cutoff only applies to tropes originating with Television. Anything else has to be Older Than Cable TV, or around for more than 35 years.
But there are some tropes that are really young, that still have that "New Trope Smell" — sometimes as recent as the Turn of the Millennium. Anything that has its origin after 1980 is one of The Newest Ones in the Book.
Of course it's hard to tell just how old a trope is, and it may turn out some we thought were new were actually older. Or some may turn out not to be that old, so they belong here. Some may have a clear beginning past this point, likely due to the Trope Maker being recent. Either way, it's a trope that simply didn't exist, at least in the way we know it, before Disco died.

Compare Newer Than They Think.
- '80s Hair: Because The '70s had its own hair looks.
- '90s Hair: The evolution of the former trope.
- The Abridged Series: Since the Trope Maker is just a few years old. And if you count The Complete Works of William Shakespeare (abridged), that show was created in 1981, so it still counts as a "newest one in the book".
- The Ahnold: A parody of 1980s action heroes like Arnold Schwarzenegger.
- Alcubierre Drive: Professor Miguel Alcubierre proposed the drive in 1994, though the inspiration came from explanations given for Star Trek's warp drive in the technical manuals.

- Bullet Time: Originated with the obscure 1981 action film Kill And Kill Again, but now overwhelmingly associated with The Matrix films.
- Cam Whore: Webcams originated in The '90s, and as usual, The Oldest Profession kept up with the newest technology.

- Civvie Spandex: This was a trend started by Grant Morrison's run on Animal Man in 1988, and then popularized by Rogue in the 90s.

Although doomsayers claimed inspiration from the Mayan calendar, the sensational apocalyptic interpretations are much Newer Than They Think, and ethnic Maya themselves (who are still very much around, mind you) found all the hullabaloo quite baffling.
