"Cash Me Outside" girl Danielle Bergoli says video showing her getting a beatdown from her mom is the handiwork of a former bff out for revenge.

The video is graphic, showing Danielle's mom, Barbara Ann, pinning her daughter to the ground, almost like an MMA fight ... calling her a "bitch."

Sources close to Danielle's family tell TMZ ... the video was leaked by a girl who was angry because Danielle's mom kicked her out of their home.

We're told the video -- which first surfaced Tuesday on WorldStarHipHop -- captured an incident that occurred 1 to 2 years ago, which would mean Danielle would have been 11 or 12. We're told neither Danielle nor her mom remember what triggered the fight.
