oakanahno - A bad word from way back when. Oak trees use it to scream at

A bad word from way back when. Oak trees use it to scream at the sky.

I used 'oakanahno' in my math test and got sent to the principal's office.

My dog barked 'oakanahno' at the mailman. The mailman left.

I yelled it at my brother and he cried for 10 minutes.
