Kim Kardashian says the woman who attacked her with flour last night is nothing more than a "bully" ... and claims the only reason she's NOT pressing charges ... is because she's just too busy.
Kim just called in to "TMZ Live" ... and gave us the blow-by-blow about how she handled herself when a female animal activist broke on to the red carpet and attacked her at an event for her new fragrance.
Kim tells us ... she tried her best to "laugh it off" ... and refused to leave the event because she didn't want to disrespect all of the people who worked so hard to put the event together.
And while Kim says she understands the flour bomber's beliefs ... KK raised a great point -- "If you're trying to promote nonviolence towards animals ... why are you trying to be violent towards humans?"
