Smooth brained Robbie

A smooth brained robbie is an individual who is unaware of modern slang. They can try but they still won't grasp the current slang, truly they will never be hip with the teens. If you encounter a "smooth brained Robbie" do not hesitate to laugh at their incompetence, because it is funny.

Robbie: "why aren't you wearing a hat? Its cold outside."
Jeff: "oh you poor smooth brained robbie".
