Fangirling 

The reaction of a female fan when presented with references to, or the
direct presenting of, the objects of their obsession/affection. The
reaction is usually characterized by squealing, wheezing,
hyperventilating, smiling, jumping, and possibly slapping of the
nearest object (to gain attention).

“Why was Joy squealing earlier?”
“She was fangirling because the Avengers Endgame trailer was released.”

Fangirling 

Fangirling is something that one must master. It is the art of becoming so obsessed with something like fandoms, characters, actors/actresses, ships between two people/characters, shows, celebrities etc. Getting someone into fangirl mode is fairly easy too, just say something related to what a fangirl is obsessed yet and you’ll be seeing symptoms such as: Squealing, jumping, maniacal laughter, wet panties, hyperventilating, frantic waving of hands, high pitched screeching, basically having seizures while screaming, excessive movement, and spontaneous combustion.

Take me as an example with KilluGon and GonKillu.

Person: GonKillu-

*high pitched screeching* *shaking of ground and footsteps*

Person 1: What the hell is wrong with her?

Person 2: She’s fangirling... Again.

Me: *Having seizure while squealing and maniacally laughing*
