HaGa-DaGa - You say HaGa-DaGa when you're laughing because you just ruin

You say HaGa-DaGa when you're laughing because you just ruined someone's day and you're not even mad.

HaGa-DaGa, I told your secret and you’re still blushing.

HaGa-DaGa, I made your dog chase you and you’re still running.

HaGa-DaGa, I got the last piece of cake and you’re still eating the crumbs.
