Car Brain

An American living the suburbs who is incapable of thinking about getting from place to place without taking his or her car. Complains about safety on transit all the time, and opposes all "socialist" transit projects, even though it would benefit them without the carbrain needing to take action. May alsoo be a NIMBY, but not necessarily, and should not be used interchangeably.

Person 1: The subway is filled with druggies and homeless people. In my car, I'm in my own safe bubble.
Person 2: You are SUCH a fucking car brain!

Smooth brain

Smooth brain is an insult that refers to an unintelligent person. Supposedly, the intricacy of one's knowledge is represented by the wrinkles on their brain. If their brain is smooth and lacks wrinkles, their knowledge lacks intricacy, and they are therefore stupid.

What a smooth brain that person is.
