Smooth-Brained

A person who could be very well-informed and high-functioning, possibly even quite intelligent in certain areas, but is an idiot nevertheless. Usually a smooth-brained person has never thoroughly examined their beliefs, is generally susceptible to ideology, and has enjoyed a relatively comfortable life free of struggle or adversity.

Smooth-brained can also describe an article, film, or any other piece of content that presents a view of the world that betrays the author's complete alienation from any of the material conditions that define most peoples' lives.

Can also be used as a noun, for example: smooth-brain.

Did you read the latest smooth-brained think piece about rising division in America?
Nah, I can't even read that both-sides bullshit.

Smoothbrain

Smoothing out your brain will also negatively affect your intelligence and reason, this is precisely why smooth-brainers are often called "stupid hippies" or "vegans" by lower class citizens because they seem to become increasingly stupid as they level up. This will however all pay off in the end, when you reach the ultimate goal of unity with the universe. The path to godlike status is and literally goes through the "rough", which is also why around half of the worlds population decide to stay in this lower level of "rough" class brainers, which usually leads to a steady decline of their life into a criminal and abuse filled life-path, which always tends to end in horrible death.

Look at that idiot he must have a smoothbrain

Smoothbrained Skelder

An Among Us player who always plays on the Skeld map no matter what. They are often noobs or people who leave when they aren't imposters. You will usually find them in games with only one imposter and a maximum of ten players instead of the new 15-player servers.

People who play on the Skeld are fine, but if they're a Smoothbrained Skelder then it's annoying.
