The R-word, retard(ed), was used in the past to describe a person with an intellectual or developmental disability. Since then, it has morphed into a slang word to mean things like “stupid” or “idiotic.” Many people think it is socially acceptable to use the r-word in this way but the truth is, it hurts and dehumanizes those with an intellectual disability and their family and friends. The Spread the Word to End the Word movement was created to end the pejorative use of the R-word and promote dignity and respect for people with intellectual disabilities. Join the movement by pledging to end the r-word at r-word.org and vote this definition to the top.
Person 1: I'm so retarded; I forgot to get milk at the grocery store.

Person 2: Hey, I would appreciate it if you didn’t use that word around me anymore. When you use "retarded" as a synonym for "stupid" or "idiotic," you are saying that all people with intellectual disabilities are stupid, and that’s definitely not true.

It means "very stupid" but in a more hilarious, weird, and/or spontaneous way. From the Latin word for "slow".

If you want to tick off a politically correct person, just say it. They think it's mean because people with mental problems are not always stupid, except you can't call those people "retarded" in the first place, and nobody cares anyway. Plus, once again, it's from the Latin word for "slow".

The word retarded in slang means to get stupid; just act how you want to; dance like you don't know what you're doing. One normally becomes "retarded" after popping an ecstasy pill or doing some sort of drug.
