"Ah-Duh" is a combination of the "Ah-Hah" moment of realization and the "Duh!" moment of having realized something that should have already been obvious. Ah-Duh therefore captures the feeling one has when one excitedly realizes the obvious and/or believes they've had sudden insight but then realizes they have "re-realized" something they already knew to be the case.

Get the ho-ahmug. Ah man is derived from the words ah and man slung together in a wonderful, delightful phrase.
Mostly used by stoners, the said prase is an assertion of said stoner's stonerness, while also being an affirmation of something (similar to yes, but cooler).
