A person who is a fan of a particular game, brand, band, movie or any part of popular culture to the point where it becomes a way of life for them. Arguing with a fanboy is ultimately futile, as no matter how many well-articulated facts you put to them that may criticize said game, band etc. they will take it as an insult, almost as if you're insulting their child. DO NOT, under any circumstances, engage a fanboy in an intelligent discussion regarding the flaws of their favored hobbies as it will only result in one-sided arguments that you have no chance of winning.
Fanboy: I believe that Halo is one of the most amazing games to grace this earth.
Level-minded individual: Well it's not all that good, certainly not the way you're making it out to be.
Fanboy: How dare you! You're nothing more than a troll to disrespect this work of art. Go back to your cave....

A fanboy is a male person who's a big (kinda obsessive) fan of something. Fanboys often tend to know everything about the subject they're a fan of. When someone accidentally talks about the subject a fanboy is a fan of while the fanboy is within hearing distance, then that someone should run. RUN!
Someone: I just saw the first episode of my hero academia. It was kinda fun.

Fanboy: *20 feet from the conversation* DID SOMEONE SAY MY HERO ACADEMIA!?

Someone: *screams* NO! *whispers* Dude, we have to go. There's a... A f a n b o y near us

Friend of someone: Oh shi dude

Fanboy: *appears behind the two dudes who were having a conversation* Hi! So, my hero academia you said?

The two dudes: AAAAAAAAAAAAAAAAHHHHHH

One who is committed to a specific subject in a genre of popular culture such as comics, videogames, movies, ect.. in which they will defend the subject, devoid of any proper constructed criticism.
A fanboy may defend the new Star Wars movies, believing them to actually be good, despite their obvious lack of quality and intelligence when comparing them to the original trilogy. In a recent example, Harry Knowles (of aintitcoolnews.com) in 2002 claimed that Star Wars Episode II: Attack of the Clones was the best Star Wars movie to date. Did he really mean that Attack of the Clones was better than The Empire Strikes Back (agreed among many to be the best in the series)? Was Harry's statement made just so he could claim he had the minority opinion? Perhaps not, but his devotion to the Star Wars movies at the time influenced his statement a great deal, and further implemented his way of thinking. In the end, fanboys, such as Harry Knowles, will always believe that the next installment in a franchise will be better than its predecessor; thus no matter how bad something is a fanboy will always like it.

A pneumonic device in AP style for remembering words that receive commas just before them when conjoining two independent clauses. (for, and, nor, but, or, yet, so)
This is an independent clause, but this is also an independent clause.
