If you are a student of language you will appreciate the explanation of this definition. Lets look at the origins of the word. It may be a verb or noun similar to the word retard - delay, procrastinate, postpone, slow, hinder or obstruct. So if someone was a re-tard (this of course is the French pronunciation used in the Golden Globe winning film The Hangover) then it would be one who was delayed, a procrastinator, slowed, etc. The meaning of the prefix re- means to repeat, back, or again. So that if you are labeled a returd, it would designate you as someone who repeats the turding process frequently. Therefore not an individual who hinders or slows the turding process. Please feel free to apply the moniker to people as needed. I think it could be applicable to one who spews forth turds, perhaps those in elected office, in specific divisions of sales, or individuals who have not completed assigned tasks and feel the need to deny the reality that they were retarded in doing the task and so they make up excuses for the delay.
Perhaps it could be used in a sentence like this: "I was so sick of hearing all of his bogus excuses, one after the other, he is such a returd". As a verb it might be used in this way, "Man he needs to shut his mouth. The stuff he is saying is like so returded".
There are so many people and instances in which I plan to use this new term. Feel free to make it your own and use it as you see fit. Let this be my gift to you, you big returds.
