Its what someone is when they call someone else Retarded. A way to reiterate what they consider themselves but pass the blame off onto someone else. You can't have a replay without it first being played.(no pun intended rerun). Nothing can be explained to someone else without it first being understood by yourself.
A slightly derrogitory term for the use of the adjective 'retarded' meaning stupid, amusingly dumb, or almost never the real definition; mentally challenged. The word is only offesive to those without a sense of humor or if actually used offensively.
E.G. "Dude, that guy is 'tarded; he smashed up Chris' ride!
