Brain Boner

An idea.

Smooth brain

A derogatory term used to describe an individual perceived as lacking intelligence and exhibiting quickness to anger. The term is inspired by the koala, a mammal known for its aggressive behavior and cognitive limitations. Despite having a diet exclusively consisting of eucalyptus leaves, a koala might starve if presented with pre-picked eucalyptus, underscoring the reference to an extreme lack of problem-solving ability.
