Answer:
"Duh" is a word used to express a persons feelings of knowing something when another person doesn't. For instance an alternative and longer way to use "Duh" is to say the sentence "Well obviously the reason she didn't call was because she was at work" or "Of course you boil the water before you put the rice in". So basically its a word to retiorte a persons meaning of something.
