The term "Bouncy," as shorthand for this kind of post, traces its origin to DUmmie Bouncy Ball, who used to post these sorts of things frequently in DUmmieland. Now I just did a little googling, and the latest I can find a post by DUmmie Bouncy Ball is November 10, 2006. I don't know what became of DUmmie Bouncy Ball after that. Was she tombstoned? Was she disappeared? Whatever happened to Bouncy Ball?
Somebody converted her to conservatism.
