Dumbniac

It’s like braniac, but its when someone is so stupid they have actually perfected their stupidity as an art form.

Person 1: Hey brah, do you think I’m an idiot?
Person 2: Nah man, you a real dumbniac!
Person 1: Yo that’s so nice of you, thank you.
Person 2 (and person 3, suddenly appearing): *wink wink*

Dumbnacissist

Dumb-Narcissist (simplified definition)

Someone who wants to be a narcissist but isn’t smart enough to be one.

They lie constantly without realizing it, think they’re manipulating people, and believe they’re hiding their intentions really well; when in reality, everyone can see straight through them. They have big ego energy with very small skill to back it up.

Basically: all the arrogance, none of the brains.

“He keeps trying to gaslight everyone, but he’s such a dumbnacissist that it’s obvious what he’s doing.”
