You say HaGa-DaGa when you're gloating because you just outsmarted someone and they’re too dumb to realize it.
HaGa-DaGa, I took your lunch money and you didn’t even see me.
HaGa-DaGa, I got the last slice of pizza and you’re still eating the crust.
HaGa-DaGa, I knew that joke was gonna be bad, and I was right.
