Brandi Glanville isn't backing off her crusade to trash Joanna Krupa's vagina ... and when she got drunk this weekend, the attacks got even more vulgar.
TMZ cameras rolled as the "Real Housewives of Bev Hills" star was carried out of Fleming's steakhouse in L.A. -- and even though she could barely stand, Brandi managed to compare Krupa's lady parts to a certain unflattering sea creature.
Of course, Glanville first went after Krupa's lady parts on "Watch What Happens Live" last week ... when she claimed Joanna slept with Yolanda Foster’s ex-husband Mohamed Hadid … and Mohamed told her Krupa's nether region was straight up stinky.
As for Krupa ... she didn't seem too bothered this weekend, when she grabbed her husband Romain Zago and paraded around her ass by a pool in Miami.
Smells like a distraction technique.
