When someone challenges your devotion to your favorite character.
Example:

Me: You read Percy Jackson?!?!

Person: Oh yeah! I loved it! Who's your favorite character?

Me: Annabeth of COURSE!!!

Person: ....

Person: She's my favorite too....

Me: Uh, cool!

Person: I didn't think you'd... Y'know, like her. You're more of the person to like Leo.

Me: Uh, I do like him. I just REALLY like Annabeth because-

Person: Because of Percabeth?

Me: No! Because she's smart and kind and bad a- Why am I even explaining this to you?!?!

Person: I bet you don't really like her. I bet you're just trying to seem smart.

Me: ....

Me: Seem?

Person: Yeah, cause, I bet you're like ALL other girls. You really like Leo, but want to seem like you actually PAY ATTENTION to character personalities.

Me: No, I just really love Annabeth as a character...

Person: Whatever. You probably only joined the fandom for Percabeth and Leo anyway.

Me: .... *shakes violently*

Me: *turns into rampaging monster*

Person: .... You're not even a proper reader. You're a FANGIRL. FANGIRLS DONT PAY ATTENTION TO PLOT! THEY ONLY READ FOR OTPS AND HOT FICTIONAL GUYS!!! AND TO MAKE THEMSELVES SEEM SMART!!!

Me: *bites person's head off*
