Whenever a "monster" type character such as a vampire, werewolf, what have you, explains at length about the various rules/characteristics of their culture to another character (usually a clueless human). Usually this happens in one large infodump or sprinkled throughout a series to explain something that, otherwise, would not make any sense. Note that the purpose of this is more about explaining it to the reader rather than the confused human character and only counts if it becomes really obvious and or annoying.
Sometimes the human character will even continue on with a string of questions just to explain things further to the reader, turning into a rather odd interview.
Person B: Yes, because I am a half-werewolf. We have existed since the 1800s when a man by the name of...
(Several hours later.)
Person A: Okay, I wasn't that interested.
Often overlaps with Your Vampires Suck.
- Inheritance Cycle will often pause for a conversation about elves and their culture. Eragon asks a lot of questions and not all of them are plot relevant.
- Twilight: Edward Cullen spends a chapter (the infamous meadow scene) to explain vampire lore to Bella.
- Harry Potter and the Deathly Hallows, Harry is running down a list of things at Voldemort's command and when he arrives at Inferi he specifies that they are "undead bodies animated by a dark wizard". This is justified because the Dursleys did not believe the danger they were in and why they needed to leave their house for their own safety. What would scare you more, a nonsense word you don't know the meaning of (which sounds a little like "fairy") or an animated corpse controlled by dark magic?
- Seen in the world of The Birth of a Hero in Trash of the Count's Family, because their monsters have a lot of different rules compared to what's usually seen. The info is usually spread throughout the narration or in Cale's internal thoughts as he reflects on the info that was given in the original novel, but oftentimes it comes from the people themselves. Eruhaben has to explain some things to the young Dragon Raon who wasn't raised by other Dragons.
- Bill from True Blood. You can't go through one episode without him explaining yet another aspect of vampire culture to his confused human character (Sookie). By the end of the first season, he must have explained everything because he stops.
- An old Saturday Night Live sketch turned a job interview with a centaur into such an occasion, much to the centaur's chagrin.
- The first episode of Moonlight begins with Mick explaining the series's vampire rules to an unseen interviewer.
- In the beginning of Vampire: The Masquerade Bloodlines, Jack will explain the rules of the Masquerade and vampire weaknesses to fledglings. You'll also get the chance for explanations the first time you meet a Ghoul or when you meet the Kuei-Jin leader Ming-Xiao in Chinatown. Justified as this only happens if you ask for clarification (and if you don't take the opportunity to ask questions, the gaps in your knowledge can change outcomes later—for example, if you don't get certain information about ghouls from Mercurio or Knox, you can't save Heather.)
- In The Inexplicable Adventures of Bob!, the first appearances of the dragons and the bigfeet brought large infodumps from Hibachi and Goona respectively.
- Averted in The Order of the Stick: Celia (a Sylph) considers the knowledge such a monologue would provide common knowledge (even for humans) and consequently doesn't explain the traits and attributes of her species to the Order. This proves fatal for Roy, who she could have saved if she hadn't assumed he could shoot lightning from his fingers.
- Jake from Magical Border Patrol does this when explaining the nature of his.... interesting features.
