Holy Crap! The Kim Kardashian Guy Really Said, 'N****RS In Vienna'

Wow.  Kim Kardashian wasn't BSing when she said some dude at the Vienna Opera Ball said he wanted to dance to "N****rs in Vienna."

TMZ broke the story ... Kim went insane when the dude dropped the N bomb -- with an "R."  She stormed out of the ball ... a function for which she was paid $500K by some rich Austrian guy.

The guy apparently thought he was being funny, but you clearly see Kim is not amused.
