A grandmother pulled out a knife on her grandson and threatened to stab him after he laughed in her face.
An elderly woman reached into her handbag and whacked out the sharp weapon before brandishing at her young relative after he started being rude to her in her car.
In a video clip uploaded to YouTube by the user World Star Hip Hop, the granny screeches at her grandson: "Shut the f*** up. I'll stick it up all the way up your goddamn a**!
"Shut the f*** up. You ain't gon' do me like that, I will f*** your a** up, shut the f*** up, shut the f*** up now."
It's not known what caused the altercation or whether the police were called to the scene.
