This is a edit of a 5 minute video that at one time was on the quadjacks.com youtube page. It was taken at the 2010 World Series of Poker held at the Rio Casino in Las Vegas.
And I freely admit there's doubt about whether this video complies with rules 1 and 2 of this thread. With rule #2, I can't be sure but I don't think the cameraman even noticed the slip. The person who edited the video obviously did. I've seen a few other interviews done at the same event where the 'pre-interview' was not put up. Here it was. I'm assuming this is the only video in which it was. And yes there's the caption "Erin: nip slip princess". Again, done by the editor, not necessarily the cameraman. I left out part of the interview in which Erin admits turning a pool that wasn't topless into one that was earlier that day. So yes, she is an exhibitionist, but look at the move she pulls right before the interview starts. I really don't think she wanted her boobs on display on camera, and she would probably assume the 'pre-interview' wouldn't show up on the finished product. But that's just my opinion. If yours differs I won't argue.
Anyway, it's an awesome nip slip. Enjoy.
