There are actually two definitions for the phrase negative retarded.
1.) More retarded than retarded. (The superlative form of retarded)
2.) If used in the proper context, it can be a way to call someone intelligent. This is because the negative of something is usually the opposite, so the negative of retarded is intelligent.
