I know not - A loud, angry way of saying you're sick of hearing the same

A loud, angry way of saying you're sick of hearing the same thing again and again. Usually yelled at a teacher or parent who won't stop bugging you.

"I KNOW NOT WHAT YOU'RE TALKIN' ABOUT, MRS. SMITH!" (said by a kid during math class.)

"I KNOW NOT WHY YOU'VE HAD TO TELL ME TO DO MY WORK FIVE TIMES!" (said by a kid after being nagged for ten minutes.)

"I KNOW NOT THAT I'VE HEARD THIS SHIT BEFORE!" (said by a kid during the fifth reminder of the day.)
