Joseline Hernandez & 'Love & Hip Hop: Atlanta' Fight -- Cast Wants Her FIRED

Smack talk about crack triggered the all-out brawl on the "Love & Hip Hop: Atlanta" set ... ending with a security guard getting a piece of flesh ripped off his body... and they say Joseline Hernandez is the culprit and they want her FIRED.

Cast and crew who were present during the melee tell TMZ ... Tuesday night's fight started when Benzino called Stevie J a crackhead. Stevie J then charged Benzino, yelling "f*** you."

Stevie J's GF Joseline then amped things up by attacking Benzino's wife Althea, punching her in the face so hard everyone around heard a crack. Joseline then pulled out part of Althea's weave.

But Joseline's handiwork wasn't done ... Joseline then made a beeline for Waka Flocka Flame's wife, Tami -- yanking out Tami's pony tail weave. Waka's mom Debra jumped in, punching Joseline in the head and ripping out her extensions.

Security then booted Joseline from the set. On her way out she passed shower-rod queen Mimi Faust in the stairway ... elbowing her in the back and shoving her down the stairs.

The security guard tried to subdue Joseline, who then bit the guard, ripping off a piece of flesh.
