To be stupid. Not very clever, most likely to be lacking in intelligence

One who has a mania for music.

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.

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.

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.

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.

1. A word for some one with a low iQ.

2. The Welsh word for carrot.
