Kim K to TMZ: Kiss My Big Fat Ass!

Don't call Kimmie "spoiled" -- she prefers going by "disgusting ... cottage cheese stuffed in a trash bag."

Her former BFF Paris Hilton trashed her booty all over a Las Vegas radio station yesterday, but all Kim cared about was being called a "spoiled brat" by TMZ.

Actually Kim, we called you a "spoiled bitch," and we're stickin' by our story.
