I Am Not Spock: This movie caused a few people to mistakenly think Helen and Christian Slater were brother and sister in real life.
Les Yay: The girls who cut their hair to look like Billie Jean often seem to really, really admire her.
Memetic Badass: Billie Jean is this in-universe and out. The fact that many people's first impression of her is giving Hubie a Groin Attack and escaping several adults chasing her in the mall probably helps.
Memetic Mutation: Before a DVD was eventually released, plenty of fans clamoured for it by saying "fair is fair!"
Moral Event Horizon: When Mr. Pyatt tries to have his way with Billie Jean in the attic. Later, Hubie attacking her in the mall. Man, what is wrong with that family?
Narm Charm: The movie is cheesy, contrived and incredibly 80s, and fans wouldn't have it any other way.
Unintentionally Unsympathetic: Binx is generally a hothead, and does a lot to exacerbate the situation. In fact, he's the one to carelessly shoot Mr. Pyatt and kick off the whole mess. And then he pulls a (toy) gun on real police. Easy, tiger!
Vindicated by Cable: Flopped at the box office, but became a favorite of HBO and similar channels.
