'Gypsy Sisters' -- Brutal Girl on Girl Beat Down [Video]

Nothing new in West Virginia -- just a couple of cousin/sisters beating the bejesus out of each other on a front lawn, while the rest of the family cheers them on ... and TMZ has the footage.

The brawlers are both stars on the TLC show "Gypsy Sisters" (which airs it's season 2 premiere on Thursday) and features a woman named Nettie beating the living crap out of a woman named Kayla.

It's unclear what they were fighting over ... but who cares -- it's got punches, slaps, hair pulling, humiliating face squeezing ... and some serious smack talk.
