A synonym to the term "retard" that is used to help the user appear more
politically correct, but not as
politically correct as "mentally
handicapped". Some people view it as an exercise of a "half ass" mentality, unable to stick to one's belief or judgments fully, thus meeting in some sort of middle ground.
Some people have also been cited to use rahtard in place of retard simply because they cannot spell "mentally handicapped", and they do not wish to appear "mean".
