Simply put it's whenever a character for some reason, has a list being made of people they don't like. This list doesn't have to be shown nor does what they plan on doing with those people ever have to be said. Compare Rogues Gallery, the out-of-universe version, and Gotta Kill Them All.
- In the film Jimmy Hollywood down-on-his-luck actor Jimmy (Joe Pesci) has a catchphrase for this: "You're out of the Oscar speech!"
- In Billy Madison, Billy calls up an old high school acquaintance (played by Steve Buscemi) to apologize for treating him poorly years ago. After the phone call, a thoughtful look appears on Buscemi's face, and he crosses Billy's name off of a list titled "People To Kill." This turns out to be a very good thing.
- In the 1970 version of The Out Of Towners, Jack Lemmon's character makes out an ever-growing list of people and institutions who are making his stay in New York miserable.
- In the film The Devil and Miss Jones, the tycoon going undercover as an employee discusses keeping one with a fellow employee, an old lady (I don't remember if she kept one or if one talked the other into keeping one, but their immediate supervisor is put on the list, and the old lady doesn't realize the tycoon has the power to do something about it).
- Arya Stark in A Song of Ice and Fire has a long list of people she wants to kill, which she recites every night before falling asleep, bordering on a Madness Mantra. After the Starks fall out of grace and Arya is forced to flee for her life, she murmurs a list of people she considers responsible for her suffering as a sort of promise to herself to take revenge on them. Other people point out how disturbing this is for a nine-year-old girl.
""Weese," she would whisper, first of all. "Dunsen, Chiswyck, Polliver, Raff the Sweetling. The Tickler and the Hound. Ser Gregor, Ser Armory, Ser Ilyn, Ser Meryn, King Joffrey, Queen Cersei.""
- In The Big Bang Theory Sheldon has a list of his "mortal enemies". It's said to be extensive, and includes his grade school bully that put a Mexican peso up his nose (it's still there) and Wil Wheaton.

- Stephen Colbert has two separate lists on The Colbert Report. The first is his On Notice list. If the person (or thing) on the list does not apologize to him, then it is moved to his second enemies list, his Dead To Me list.

- Champions supplement C.L.O.W.N. (Criminal Legion Of Wacky Non-conformists).
- The C.L.O.W.N. member Tag has pictures of superheroes and supervillains in his room with red bullseyes and the notation "I owe you one!" scrawled on them. A pictorial list, as it were.
- Because of their long history of conflicts, C.L.O.W.N. is on V.I.P.E.R.'s "Top Ten to Trash" list.
- Warhammer: The entire race of Dwarves in the Warhammer [fantasy] universe each have a personal as well as racial "book of grudges" that they keep for generations. The grudges in said book can be anything from a small slight, to a major event, but all are held up with equal contempt to the person(s) or race(s) that caused the grudge. Dwarves really have a lot of enemies.
- The Mikado has the titular character making a list of all the people (more, classes of people) who he believes should be executed, and sings a song about it no less (since it's an opera).
The Mikado: "I'm sure they'd not be missed! / I've got them on my list."

- Black Mage in 8-Bit Theater has one.

Homer promptly adds the company to his revenge list, which includes (among other things) Stern Lecture Plumbing (the plumbing service he had to deal with at the beginning of the episode), God, gravity, the Bill of Rights, Grandpa, and "the boy" (Bart).
- Animaniacs had a stuck up character named Charlton Woodchuck. Whom, when feeling put-upon, would ask people to write their name in a book he carries about. Then he'd say "Thank you. When I'm famous I'll make it a point not to like you."
- Dan on the show Dan VS has a Revenge List, for everything that he wants to take revenge on. This includes anything from William Shatner to Whatever's Causing That Rash .
