The true definition is delay or hold back in terms of progress, development, or accomplishment. It has grown a negative connotation when used for mentally challenged folks. It is better defined by someone who is fully capable of developing morally, logically, or emotionally but does not. Mentally challenged are likely doing the best they can and there for the opposite given circumstances
Sarah Palin is retarded by her hate and desire to be right that she never actually checked Obama's birth certificate. The fighters who took the Jake Paul fight are retarded by the contracts financial stipulations. The Karen who called the kid at the playground the Nword went full racist retard because of her entitlement and immoral belief of superiority. Karens are too retarded to be allowed to raise children, they'll just make more retards. Which retard should I vote for president? Retarded by intolerance, retarded by Aipac and lobbyists, or retarded by complete inexperience.

Get the Retardmug. A name for a fuckhead at school. Also, you can use retarded instead. Never tell your teacher that they are a retard or call them retarded, you will get in sooo much trouble.
