duh

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.

Him: Hey, to insert a column you have to press the column insert menu!
Me: Duh! No kidding!

duh

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.

George Bush's tenure would have to be measured in yottaduhs.

Duh

A word someone says when they're being condescending, even if the situation does not call for it.

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.

Duh

The sound a retard makes.

1. Used to indicate that something is so obvious that even a retard could figure it out.

2. Shorthand for, “How did I not think of that? I am such an idiot!”

Duh! What was I thinking?
