A mystical, seemingly non-sense word joyfully repeated several times in the infamous "manamana" music video featuring wonderful muppets. Only true muppets understand this fuzzy concept. Heehee!
Manamana! Too-do-to-do-to, Manamana! to-do-to-do-to...

Originally created by the muppets, this rather addictive and annoying song also appeared on a Coca Cola commercial, where it became more familiar in the public eye. Its really annoying at times.
Person 1: MANAMANA!
Person 2: Doot-doo, do, do, do...
Person 3: God, you're all so damn annoying.
