A talkative, boob-flashing society gal was on a mission last night -- to get arrested!

After an "American Beauty" inspired make-out session with a valet, the rose-eating woman was cited for walking into the street -- and then placed in a police cruiser after she couldn't come up with her ID.

While the last drunk girl encountered by TMZ screamed bloody murder when she was arrested, this lovely lass was in heaven, screaming, "Little do you know, I enjoy all of this ... I have a cop fetish!"

UPDATE: The woman in the video has been identified as Jupiter Mendoza, a contestant on "Pirate Master." Land ho!
