Infodumping is a type of {{Exposition}} that is particularly long or wordy. Although it can be done in a way that is unintrusive or entertaining, most infodumps are [[CaptainObvious obvious]], intrusive, [[ViewersAreMorons patronizing]], and sometimes downright boring. Specifically, if the premise of your story is laughably ridiculous, an infodump will call attention to the fact. The absolute worst is the gratuitous infodump, which painfully restates that which has already been adequately shown, just to make the reader suffer. For these reasons, 'infodump' is often used as a pejorative. Even worse, one character may be [[AsYouKnow saying it to another who is fully aware of it already]], for no good reason besides filling in the audience.

Intensive infodumping about the world itself (called {{Expospeak}}) is most commonly used in SpeculativeFiction, where the reader cannot necessarily make assumptions about the way the fictional universe works. Some Speculative Fiction writers, such as Creator/TerryPratchett and Creator/DouglasAdams, make a virtue of their infodumping (which can sometimes go on for ''pages'') by making it funny and therefore pleasurable to read. Writers of less comedic works must work hard to avoid heavy infodumping unless they are ''sure'' that they can make it entertaining. Many choose to avoid intensive infodumping altogether through the use of [[AllThereInTheManual supplemental material]]. If the character does it repeatedly, then he or she is MrExposition.

In a video game, infodumps are normally in the form of a long, boring lecture from one of the characters babbling on and on, giving you pages and pages of trivial information that may or may not be useful to the player. May include ShallIRepeatThat
