gaddakadak
A ridiculous way of talking that makes your brain hurt, like someone screamed Afrikaans into a blender and it came out as 'gaddakadak'.
My teacher said 'gaddakadak' instead of explaining math. I cried.
He texted me 'gaddakadak' during lunch. I threw my sandwich at him.
The kid in my class says 'gaddakadak' whenever he’s confused. It’s annoying.
