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.
