kah tif - A very mean way to tell someone to leave, like throwing them

A very mean way to tell someone to leave, like throwing them out of your house with a boot.

'Kah tif!' I screamed when my cousin took my favorite video game.

At the park, I told the kid 'Kah tif!' for stealing my ball.

My friend said 'Kah tif!' to the teacher when she gave him extra homework.
