A person who is so stupid they dont deserve being called a reatard once but twice in the same word. This can also be used when the words fucktard, dumbass, and moron just cant portray and person's lack of simple intellegence.

This is someone who knows IT and computers but nothing else but pretends expertise in everything!

Someone who is stupid, but in an annoying way. In fact, if they were actually mentally retarded it would be a dramatic improvement.
