look up any word, like muddin:
 
1.
A retarded realtor, aka all realtors.
The Realtard fooled me into paying $500k for a 1 bedroom condo in Miami in 2006, claiming that real estate "ALWAYS GOES UP!" The Realtard got a 6% commission off of that sale, for a total of $30k in his pocket. Here I sit in 2010, squatting in my pre-foreclosure condo which is now only worth $200k.

2.
A person which is an authenticated retard. Not the morons you see everyday at your place of employment. Realtards are the real thing.
1. "The guys at work are retards... but that guy... now he is a realtard."

2. "I thought you were just another retard... but you really are a realtard."

3.
Someone who is operating in society and appears, by all means, to be "normal" and fully functional in their mental capacities. This person is not diagnosed as mentally challenged or retarded in any way, and yet they find ways to do things that are so stupid and moronic that they end up hurting themselves, ruining their careers and/or getting themselves posted on the news, YouTube and other social medias. The act is so bad, that it is disrespectful to those people in this world that actually do have mental retardation and/or are mentally challenged.
Example 1:
Did you hear about Plaxico Buress, the NFL player? He shot HIMSELF in the leg at a nightclub and now he's going to prison for 2 years. Man, that guy is a realtard.

Example 2:
That Tiger guy is a Realtard, he was the greatest golfer in the world and was on pace to break the record for Majors, but he could not keep it in his pants. When his wife found out, she chased him down the street with his own clubs and beat the shit out of his car until he crashed into a tree. That's about as Realtarded as it gets...
