Ka-Burn
The ultimate insult scream, like when you say something so mean it hurts their feelings and they cry.
'Ka-Burn!' I shouted when my brother said I was 'worse than a broken toaster.'
My mom called me a 'disgrace,' so I did a Ka-Burn that shook the whole house.
I said my friend was 'smelly and stupid,' and they did a Ka-Burn that made the dog run away.
