Smooth Brain

The term "Smooth Brain" refers to someone unintelligent, or an action that could be classified as unintelligent. Neuroscientists believe that the more folds your brain has, the more surface area neurons have, thus, leading to higher intelligence. However, without these folds, there won't be as large of a surface area for your neurons, which leads to idiocy, or Smooth Brainedness.

"This buttery smooth brained idiot stuck a goddamn fork in the power outlet."
"That was the most smooth brained sentence I've ever stumbled across in my 25 years on this planet."
