An exclamation used when your actions go unexpectedly wrong and result in an extremely annoying situation; used to place the blame for the situation that you have caused yourself onto Ned Flanders.
*You're trying to assemble your backyard barbecue when you bump into your wheelbarrow full of bricks, and they fall into the wet cement*
YOU: Ah, stupid Flanders!
YOU: Ah, stupid Flanders!
