The complete absence of restriction granted to any attractive intoxicated female who is desired by mostly everyone in any social situation. A exception from normal and acceptable behavior given to another person to do whatever she pleases, based solely on her desirable, and often slutty appearance.
That hot, drunk, chickdancing on the bar just knocked over everyone's drinks, puked a little and all of the guys are cheering for more and buying her more shots. I guess she's got tarte blanche tonight.
