Mad genital
A Mad Genital is when someone lights their pubes on fire during sex and then smacks their partner's face with it like they're trying to burn the whole room down.
My cousin tried to do a Mad Genital and set my aunt's hair on fire.
He lit his pubes on fire and slapped me in the face. I still smell like campfire.
She did a Mad Genital and I got a third-degree burn on my cheek.
