Someone who is retarded and gets fucked all the time. Also known as a "retarded fucker" or "tarded fucker". Starting being used by rednecks during the "shit on me" protests in 1989.
well this guy, hes SO retarded he dyed his hair red and denied it, and he was on a field trip singing centerfold. EVERYONE agrees that he is a fucking retard, or a fucktard.
an insult used mainly when no other can be thought of, derived from the words fuck and retard, a fucktard is someone who has done something that would match the characteristics of someoen who is mentally challenged
