Ran Ran Ruu is a term used by Ronald McDonald to signal extreme boasts of happiness. He 1st used it a Japanese McDonalds commercial, and has since become a popular meme there. Several Japanese have made video remixes of music from games and anime that feature Ronald saying Ran Ran Ruu, so many that they are everywhere on Youtube. These videos (called Ronald McDonald Insanity or McRolls) cause people to loose their sanity and join Ronald's cause.
