DAH feeling is a once in a blue moon event, in which you and 2-3 of your good friends acquire a random outburst of happiness. DAH feeling comes naturally, but more likely in places such as the Diner, either in Monroe or Westfield, Panera Bread, or in a friends basement. When you have DAH feeling, you may make decisions in which you would not normally make.
Dude remember i did taht triple salcow into a flying 69? Yeah i had such DAH feeling.
