Get the Fanboy/Fangirl mug.
anyone who is particularly obsessed with a certain book, movie, series, band or team to the extent of mentioning them in every conversation wearing merch/advertising them, attending multiple concerts/games/showings and generally freaking out at the mention of their particular obsession, even sometimes to an extent that could be considered crazy by others.

Noun: A person who likes a celebrity, band, tv show, book series, franchise, etc a lot. It can range from being obsessed in the way that gives them a bad reputation, or can just be someone who just wants to enjoy something with their friends. (Or alone. Either way is fine)

Verb: ‘To Fangirl’ To participate in the act of being a Fangirl/fanboy. This may include making fanfiction, making fanart, shipping or simping, or even just squealing over things. It varies greatly be how active you are in that ‘fandom’, or what skill sets you have, or other things.

Note: There are no rules for this. If you think of yourself as a Fangirl for something, you are. You do you. You don’t have to fulfill certain requirements, you just have to like something enough to...well...squeal over it (squealing out loud not required)

Emmie is busy fangirling, so she can’t join the chat right now. A new video was just posted of her favorite celebrity.”

“Every Fangirl/fanboy loves it when their ship becomes canon.”
