Top Definition
A person born with a mental condition and therefore has to work a million times harder to be able to do simple things (such as learn and communicate) that we take for granted. On top of this, a retard will usually suffer a lot of ridicule from society because people fear what they do not understand. The people who choose to make fun of the mental retarded tend to be complete morons and cannot comprehend that these people have feelings and emotions just like anyone else.
I find it amusing that saying somebody has cancer would not be taken as a joke and yet, using another disease such as mental retarded as an insult is common among society, and many do not realize that it is very offensive and that there is something seriously wrong about it.

Any person who's mental deficiency has lowered his IQ to 70 or less. Retarded people usually have a very limited vocabulary and often times have trouble understanding reason or logic especially if the person speaking to the retard has an above average intelligence. Retards who's intellect has been severely impared sometimes make unnatural or spontaneous motions with their limbs which make other people uncomfortable. Speech may also be affected by mental retardation causing constant stuttering and mispronunciation of easy words. Retards can be considered by some as almost "inhuman." This is due to the fact that retards can not understand basic philosophy and have no perception of things they haven't physically experienced themselves such as the atom or the concept of infinity. Mentally retarded people should not be brought to public places like churches or public performances where much like babies, they can cause a disturbance due to noise.
Child: "Mommy why is that kid in the middle row making all those weird noises?"
Mother: "Don't worry Jimmy, he's just a retard."

(R)eply (E)veryone (tard)

Someone who has not mastered the very simple difference between email's "reply" and "reply all" actions. The RE-tard is consistently spamming a distribution list's mailbox with their comment, which is relevant only to them and the sender. A true RE-tard will do this even when the original sender of an email to many people list explicitly requests recipients do not "reply all."
I can't stand it when a new system rolls out at my job. My AVP boss always spams her stupid questions to the whole company like the RE-tard she is.

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.
