lessence 

The lack of character or poor quality of a person when they are never able to be average or more than most people. It's pretty sad when someone is cursed with this.

Mark's lessence when it came to school and sports always meant he'd be picked last.

An insult generally used to call another person stupid. Derives from the medical term for smooth-brainedness (lissencephaly). A harder-hitting form of the term "smooth-brain."

Adam: If pro is the opposite of con, what is the opposite of progress?
David: Dude, you're such a fucking lissencephaloid.
