A kingdom of fans

A fandom is simply the definition of selling your soul to the devil. It's unreversible. Choose your fandom(s) wisely.

Know that when you join a fandom, people will have many different opinions like per say twenty one pilots. When fanfictions are written for the fandom, it sparks controversy due to people thinking Josh tops or Tyler tops. (Warning: if you join the TØP fandom, you will become trash. If you are already trash, you will become ever more irrelevant because this fandom is time consuming. Say goodbye to any other social life that isn't within the fandom)

But in short that's not so short, a fandom is a community of people who come together that have a common interest. Pretty much the fanbase of a book/movie/show/band

Fun Fact!: a bandom is a combination of band and fandom, together making bandom so if you like P!ATD or PTV then you're apart of the bandom

A Fandom is a group of people who have band together to become a group of overly obsessed super fans. Normally a fandom starts when a new and very good band, movie, book, or tv show becomes popular. Fandoms can sometimes be dangerous as they will do anything to meet their idol; band member, author, or actor. Fandoms are generally made up of many different types of people, such as those in the Harry Potter fandom. Other fandoms, such as the Directioners and 5Saucers are mainly young, teenage, and college age girls with the exception of a few fanboys and older adults. Many people think of their fandom as a second family and because of that, many people meet Internet Besties. Many fandoms thrive when Twitter wars arise.

The microcosm made up of people who are fans of a fiction genre, or of a subgenre, who have their own clubs, conventions and amateur magazines (fanzines), dating back (in some cases) to the early 1930s. Some of these are overlapping. Star Trek fandom, for example, started in science fiction fandom and eventually became a separate fandom on its own. Comics fandom and even rock (music) fandom also started there before becoming separate entities.

Plural Term of the word Fandom, refering to a community or group of fans of a television show, movie, book or other media. Most commonly used to describe fan produced media groups, such as fanfiction or fanvids.

Fans usually use the term in relation to belonging to a fan group, as an territorial identifier from one community to the next, ie: "I've come across the term whumping in the SGA fandom, but we don't use that term often in the Buffy fandom."
