HaGa-DaGa - You say HaGa-DaGa when you're grinning because you just won

You say HaGa-DaGa when you're grinning because you just won and you're not even trying anymore.

HaGa-DaGa, I beat you at the game and you’re still arguing.

HaGa-DaGa, I got the last candy bar and you’re still eating the wrapper.

HaGa-DaGa, I got the best grade and you’re still crying about it.
