look up any word, like smh:
 
36.
A word originally found in the dictionary, and used as a generic term for those who are mentally handicapped.

This word has now become taboo and considered a social faux-pas for the usage of those with mental disabilities, due to advancements in mental exploration and the explosive usage of the word as a negative term for those who venture from the "norm" in any way, in so much as wearing the wrong shirt or saying the wrong thing, in everyday society. It has even become a pop-culture word used to describe people who do foolish or say foolish things, whether the person stating the term is using it in a jovial or malicious way (between friends or just to be a total jerk)
1. "Did you hear what Jimmy said? He is such a fuckin' retard!"
2. "Don't be retarded, if you jump into the water from this height you will hurt yourself."
3. Person 1: "Ha, look at that retard, look how he's trying to get a job and fit in with normal society, what a freak!"
Person 2: "Yo, that kid has a mental disability and is just trying to live his life like anyone else. He's probably a better worker than YOUR retarded ass! Leave him alone and stop being ignorant."

ReTard n. Portmanteu of "Republican" and "retard". Someone who, intoxicated by an assumption about being knowlegable and right about politics and economics, forgets that they need to get actual real ordinary people to support them if their agenda is to be advanced. Often but not always middle class, easily led and with poor insight to society's problems, and naive about the mechanics of politics and utterly ignorant about how power actually works.

Someone who is arrogant, self-righteous, and over-talkative. This person thinks highly of him or herself, but realistically knows nothing other than how to whore for attention.

Not to be confused with the definition of stupid or naive.
My neighbor is naive, so I get why he sometimes does things that are stupid. Sarah Palin is a true retard, so I get why SNL made fun of her.

The modern equivalent of attention-whoring, infiltrating reactionary College Republicans: In the 1980's people like Grover Norquist, Jack Abramoff and Ralph Reed infiltrated college campuses passing out phony-populist, pro-corporatist and anti-leftist pamphlets and material. This was counter and reactionary to the counterculture or hippie movement a decade earlier. Today they do this kind of thing on the internet, infiltrating forums and other websites, proselytizing their backward messages. We already know what the R stands for, the etard is the web equivalent of these types.
FreedomWorks maintains an army of R-etards to constantly whine and bitch about the federal government in their relentless proection of the profits of companies who outsource jobs.
