A full retard is a person that is retarded to a greater extent, or an individual that spazzes out uncontrollably from excitement that would mimic a person with Down Syndrome. A person that goes full retard that is retarded can be incredibly dangerous, as they can generally black out from emotions such as rage if under emotional distress or if they feel threatened they will have a loss of physical arm movements and can feel no pain. If they start winding up a windmill punch and it happens to connect, it can be incredibly devastating, if not lethal, to the individual receiving the blow. A person without the physical retard strength that can go full retard will have a loss of neck control and will make a lot of noise.

Did you see that homeless dude go full retard when those guys took his sandwich? I thought he was getting hyphy until I realized he was actually retarded.
