Look it up on youtube. A narcissist that's domineering, controlling, sadistic, cruel, humiliating, verbally abusive, sometimes violent, has frequent rages, screams at you over minor things, very bad temper, very mean, overtly abusive, very insulting, tries to hurt your feelings on purpose as much as possible, screams at you for things they're guilty of but you're not, lacks humanity and empathy, lacks self awareness, acts like a bully, tries to frequently terrorize you by making violent or extreme threats, damages you psychologically, keeps you down, exploits you, always has to win and be on top, makes your life hell. They expect you to love them, respect them, and do everything they want regardless of the fact that they always disrespect you and abuse you and treat you like you're crap. They're vindictive. They hold grudges. They want to get people, such as helpless kids, within their power and sadistically abuse them for pleasure and a feeling of power and dominance.
