An individual who can not coherently participate in and contribute to society. An idiot is considered 'less', and not respected by his peers. One may use the term 'idiot' when referring to a classmate or coworker when they make mistakes repeatedly, or say the most ridiculous of things.
One who is so privileged that they are able to deny hard truths about the world such as global warming and the facts about gender, race and the lgbt community.
Some white wealthy loser: global warming doesn't exist. If women are equal then can I punch you now. Trans folk are a threat<things idiots would say
