Fanboy

1. Someone who is male and obsessed with a show, comic, movie, band, etc. They know everything about it and will take any chance to talk about it.

2. Someone who is male and very nerdy and geeky. They often write fan fiction or draw fan art of their obsessions.

3. Someone who is very stubborn and will defend the franchise of their obsession with their dying breath. Can often be obnoxious and unopen to other opinions, often a teenager or young adult.

Most fanboys are one of these or some combination of all of them. They're often neurodivergent in some way and spend a lot of time online interacting with fellow fans. Common fandoms are Star Wars, Star Trek, Dr. Who, Twilight, Divergent, Hunger Games, and Harry Potter just to name a few.
