"Fool Moon - The Dresden Files, Book 2" Chapter 15:
"I could have sworn I saw her face start to change, her bared teeth begin to grow into fangs. Maybe that was just the effect of the magic on my perceptions, though, or a primitive, lizard-brain sort of reaction to Tera rising to her feet and charging toward me with a howl. There was murder in her eyes. I hadn’t gotten beaten up twice, shot, and nearly strangled to get taken out by a misguided werewolf bitch."

Get the Slut For Brainsmug. Opposite of big brain. Smooth brain refers to an idiot or someone dumb. Neuroscientists believe the more folds you have in your brain means the smarter you are. Therefore if you are called smooth brain, you have less folds and therefore dumb.
How did you forget to lock the door? Good move, smooth brain.
