Nigger Brain

The tendency for a normally smart and well-adjusted black American to suddenly and inexplicably become hostile or incapable of rational thought. Often happens during puberty or during their late teens/early 20's. Once afflicted, the symptoms tend to be irreversible. Symptoms include becoming hyper religious, falling for black nationalist rhetoric, becoming physically violent, throwing away close friendships with anyone who isn't dumb and ignorant, and generally giving black Americans as a whole a bad name.

Bill: Yo, you hear what happened to Karmelo?

Kai: I haven't heard from him in years. Dude was always pretty chill and fun to hang out with. What happened?

Bill: He got a bad case of nigger brain. Stabbed a kid at a track meet out of nowhere for no reason.

Kai: You serious? Bro, what is up with all these cases of nigger brain? Is it an actual disease or something?

Bill: Must be. We all know he's not the only young black person to flip their lid and go crazy over nothing out of nowhere.

Arc Brain

To completely space out and lose yourself mentally in a fictional scenario, plot or thought. The source of the thoughts can either be internal or external, such as a movie plot or just a conversation about a certain topic.

Multiple people people can be affected by arc brain together if they mindlessly continue rabbling, spouting coherent nonsense but yet still understanding one another, somehow sticking to the original topic.

An example of this phenomena could be when you watch a film with a friend and you notice that one of you have been staring into the void, sitting completely still and silent. Then suddenly that person presents a sub plot about something unimportant or an extremely detailed analysis of something completely irrelevant to the film.

Arc brain commonly happens while under the influence of marijuana.

While watching Encanto, "How do you think the villages local economy is affected by the loss of the madrigal family's magical power?"

"Sheesh man I don't know. Solid arc brain though."
