Believing you and your life are either literally or metaphorically the center of a metaphysical narrative in which you are the protagonist and that your life obstacles or people you disagree with or dislike are forces of evil. Most often seen in people who have consumed large amounts of entertainment such as books, movies, or video games which have a concrete "good or bad" for most of their lives.

She is perfect in every single thing she does and has no flaws or vulnerabilities. She never has need of male acceptance or approval of any kind because SHE DON’T NEED NO MAN. She is a warrior. She is a goddess. She is...Strong Female Protagonist™️.
Man #1: Dammmn, look at the ass on that one, bruh. Man #2: You better keep that shit to yourself, man. That’s Strong Female Protagonist™️. If you sexualize her, she’ll cut your nuts off and feed them to you. But she won’t feed them to you in the kitchen because a woman doesn’t have to belong in the kitchen. Man #1: Man, fuck this shit.
