Anyone driving a car and doesn't know what the fucking blinker is for.

i don't have a definition, i just thought it was funny that the second definition uses the word "stupider" to describe someone who is a moron.

A person who is lacking intellectual capacity and general common sense.
This slang word is mostly used in a derogatory sense.

Moron was originally a scientific term, coined by psychologist Henry Goddard from a Greek word meaning "foolish" and used to describe a person with a genetically determined mental age between 8 and 12 on the Binet scale. It was also once applied to people with an IQ of 51-70 and was a step up from "imbecile" (IQ of 26-50) and two steps up from "idiot" (IQ of 0-25). The word moron, along with "retarded" and "feeble-minded" (among others), was once considered a valid descriptor in the psychological community, though these words have all now passed into common slang use, exclusively in a detrimental context.

Someone that refuses to read the above statement:
"Don't name your friends. We'll reject inside jokes and definitions naming non-celebrities."
But still writes their boyfriend's/girlfriend's and/or best friend's name. Usually starts an entry with "The most amazing person you'll ever meet!"

Makes it very annoying for those of us that screen through these entries.

Someone who, in submitting an urban dictionary entry, doesn't quite get the concept that you are trying to define something, not make an argument in favor of it or write a commercial for it.

One of the most overused insults on the Internet. Requires only a basic grasp of the English language to use and zero intelligence or creativity.
