Nahhhhh 

This is the phrase you give when you "politely" refuse to donate money to a canser fund, even if it is only 1 dallor...you have to say it with a smile, and laugh alittle, while being serious at the same time to get the full effect.Also, the longer you extend the Nahhh, the better the effect.

"sir, would you like to donate money to the Berkshire Canser Fund?"....(smiles and says) "Nahhhhhhhhhhhhhh"
