Get the Fanboimug. 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

Get the Fanboymug. A "dude" that never gets laid, or fucked his cousin when he was 16. He wears a worn out Punisher t-shirt to claim his stake as First and plans his costume for Comic Con ten months in advance. Lives in the basement of his parents house with his SEGA gaming console which is better than any other gaming console, dude! Gets excited and waves his arms a lot over stupid shit no one cares about. Probably played a animal in a community theater production at some point.
