The sisters whose river rafting brawl video went viral are blaming their violent, yet hysterical fight on booze and bitchiness -- and say it could end up costing them their jobs. 

Sisters/sparring partners Jessica and Jasmine Boling tell TMZ their rafting expedition down the Nantahala River in NC went south when they squabbled over who was going to guide the raft.

It also didn't help that they'd been drinking earlier. They say the fight continued long after the clip ends ... and Jasmine had to be dropped off mid-river because she was too wasted and aggro. 

While they eventually hugged it out ... the real problem is they work for the company they were rafting with during the fight. Even though they weren't on the clock, they tell us Big Creek Expeditions isn't stoked about the bad pr ... so they could get fired.

A Big Creek rep tells us they're still deciding what, if anything, to do to the sisters -- who claim they're normally "really sweet." We're sure.
