Smart-Retard

A Smart-Retard is a certain person who is often incredibly intelligent in one major category of their life but a complete retard in another (business, family, social,etc)

Joseph is such a smart-retard ... He is incredibly smart when it comes to business and dealing with finances, but is a total retard when it comes to supporting his family.

retarded smart

Someone who is so smart, it's mind-boggling and makes others feel retarded in their presence.

Person 1. "Wow, man you like programmed that router in like 15 seconds and fixed the problem..."

Person 2. "Yeah, I have my moments."

Person 1. "Dude, you are retarded smart."
