look up any word, like pussy:
explained properly by my 3 year old niece to her father.
So the other day Josephine said, "Duh Dad."

I asked her what "Duh" meant and she said that "Duh is when we have an argument and then I say Duh...and then I win the argument."
She's a genius.

Duh is an exclamation denoting
room-temperature IQ. It originated in Archie comics, in which there was a stereotypically big, blond, dumb, athlete named Moose. It was said that his brain was in his big toe, implying that the only thing he was good for was kicking a football.

Everything (and I mean everything) that came out of his mouth was prefaced with "Duh!" which demonstrated that he was a complete dolt.

"Duh! Jughead! Stay away from my girl Madge!"

My mom told me I had to clean.
DUH! That's so lame.

Adding this word to the end of a sentence automatically makes the sentence true. Implies the obvious.
The moon is made of cheese, DUH!
