Moth-Brained

When a person has moths flying around in their brains, laying eggs in all the old things in their lives and clouding the lights with their bodies and egg sacks causing them to be dim-witted, lazy and unable to see clearly.

Mark is so moth-brained that when we had an actual infestation of pantry moths, rather than throwing out the food where they lay their eggs, he moved it to the other pantry. The pantry is not the problem mark, you are.

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.

Jeff: "that was awesome, no cap"
Robbie: "why aren't you wearing a hat? Its cold outside."
Jeff: "oh you poor smooth brained robbie".
