Sound used to imitate a mentally retarded person as an answer to an obvious remark or question. The person using "duh" is thereby sarcastically indicating that he/she is not retarded and the forgoing remark or question is obvious to him/her.

A basic unit of measurement of human stupidity. One "duh" is a single unit of stupidity, for example, misplacing your keys would be approximately one duh. Due to the large amounts of stupidity present in the world, more practical units are megaduhs(10^6) or gigaduhs(10^9). Still larger units such as exaduhs(10^18) or yottaduhs(10^24) are more appropriate for measuring stupidity on a global level.

Friend: I took a trip to nostalgia land
D-bag: Look on the bright side, it means more people can enjoy old anime now.
Friend: Uhh, why would I look on the bright side even though my comment never implied something negative.
D-bag: Because you need to experience the dark side to fully value the bright side.. DUH!!!
Friend: Uhh, I still don't see how any of that is relevant to my comment, you make zero sense.
D-bag: No, it means you have no common sense, DUH!!! Go back to school retard.
