(True Definition): Someone who is extremely idiotic, stupid, and moronic in their actions and words. The combination of two seperate words: 1. "Fucking" and 2. "Retard". Shortened to "Phucktard." The "ph" is used as the "f" sound so it is allowed on web sites who's administrators are touchy about profanity.
A combination of the word "fuck" and "retarded" except spelled a little differently. A phucktard is someone who is so fucking retarded it is almost not humanely possible.
