fackenell - fackenell is like when you're so mad you could punch a wall

fackenell is like when you're so mad you could punch a wall and it would be surprised.

My math test was a disaster and I said, 'Fackenell!' to the teacher.

My brother took my last slice of pizza and I yelled, 'Fackenell!' at him.

I got grounded and I screamed, 'Fackenell!' at the sky.
