hoodilydaddle
Something that you can never know anything about but believe everything you are told about it. Hoodilydaddle is a term given to anything you can't explain. It derives from things usually talked about by people in white lab coats. If you can't pronounce the name of certain things or topics just default to hoodilydaddle.
